Not sure. lol This isn't a factory mirror. I'm not sure where it came from, but I like it.

Plenty, just none that I'm moving on at the moment. Swapping a different carb tomorrow, and electronic ignition soon.

Also picking up some 15x10's tomorrow.

[gogriz91]

Which carb are you swapping in? If that's an L-18 or L-20, the SUs might work out nicely if you can find some. It looks like it's in great shape especially considering how old it is.

id love to have a 620 ... i really like these trucks.

It's an L20B. I put on a 32/36 Weber on for now.

I actually want to go the ITB route with some Keihn CVK 40's. Just haven't worked out an intake manifold just yet, but I will!

get one dude. They're literally everywhere if you're looking hard enough

[metalmatt47]

Shit man, my bandwidth died.


New pics ftw!



Wheels/tires coming up in the next few weeks.







I pulled the transmission because of a nasty scratching sound it developed when the clutch was in.











Any guesses what happened?

[F8d2Blk]

Pilot Bushing?

[Cynical 1]

good looking truck...

too bad about the crank walk...

Close. lol Actually, the real story was that since I got the truck, I was driving around on a bum u-joint with a flat spot in the bearing (replaced it when i did the clutch) and it appears that all the crazy driveline vibrations knocked out some tranny mount bolts and well... the rest is pretty obvious.


There was no REAL damage, just some battle scars.

[metalmatt47]

Yayyyyy trucks running great now.

Next step is going to be electronic ignition. Haven't decided what IGN control to use, but an MSD 6AL is screaming my name. Crank trigger with a dizzy delete would be cool too.

Also gonna pick up some 40MM CVK ITB's from a bike and hack up an old manifold to piece something together.


Last but not least my current project:




I'm stuffing this under the bed just behind the axle between the frame rails. I'm mounting it with 1'' angled steel bolted through the frame-rails at the rear, and i'm gonna weld up a cage around it for protection. Should give me some nice results.

[Saung]

Nice truck. I have a yellow 77 Toyota that I'm working on.

[metalmatt47]

Thanks man. I love old Yota's too
















I lowered mine in the front.


Before....






After....

[4g638u]

nice truck man, i like it.

[Drummerboy]

Is this torsion bar suspension? If so, what do you do to lower it? My brother has a 720 that we want to ca18 swap eventually, but we haven't really figured how to lower it yet, lol.

Yup! Torsion bars are awesome.


All he needs to do to lower his 720 is:


1: Jack the front two tires off the ground to unload the front suspension. (don't forget the stands)

2: You'll need a 15mm crescent wrench for the nut on top of the bars, and a 17mm 1/2'' drive on the head of the bold. Loosen the bolt to lower the suspension. Hold the nut on the back side, or it'll just spin.





3: Make sure when you adjust them, you do both sides in equal intervals. It's gonna be tough to match them both perfect, so it will take a few tries to match both sides. Make some measurements and do your best to match them.

4: When you drop the truck, the torsion bars settle back down pretty quickly, but going over a bump (like the gutter) a few times settles it down better. Measure and adjust.

5: Re-index the control arm bushings when you lower it. The bushings were torqued at the original height, so you'll wear them FAST if you don't re-index. It takes just a minuet to do it. All you do is break the control arm bolts loose, and re-torque them to allow the bushings to settle back in at the new height.

6: You'll need the front end aligned after you adjust them. It changes the whole front end. Camber, toe, etc.

7: The front suspension is going to feel much softer after it's dropped. Since he's using a CA18, his intent is pretty obvious. Make sure he's got a good set of shocks on the truck. Poly bushings and mounts on the sway bar help a lot also, but the T/R cannot use poly bushings!!! It will put an un-godly amount of stress on the T/R and it will likely break.


It's easy! PM me if you have any more questions. Also, get him on Ratsun.net, and he'll find an unlimited amount of knowledge on these old datto's. Some serious gear heads on there.

[Drummerboy]

That is great info! +Reps for you!

[Catnip]

Some Weber DCOE 45s would go on there nicely

[metalmatt47]

Thanks! I love reps

Some Weber DCOE 45s would go on there nicely

Only if I can find them at a good price. I have some goodies coming soon.









Started with suspension work again! Front shocks went on today, rear shocks tomorrow. The fronts were absolutely blown out.

I also scrubbed the fender wells clean and sprayed them with some cheap undercoating.

[metalmatt47]

ahhhhhhh mother fucker.

Lost my rear brakes due to a trashed rear wheel cylinder. It uses a two piece that bolts a second part on the back of the wheel cyl that holds the bleed screw and brake line. WELLLLL, my fucking bleed screw was broken off on BOTH sides. I didn't know until I had pulled the thing apart. Waiting on parts to come in tomorrow to put the brakes back together. Until then, this is how she sits.

[metalmatt47]

I now have a long tube header! Gonna ditch the straight pipe and go with a Summit Racing resonator. Maybe a glass pack on top depending on the volume.

[metalmatt47]

Just thought I'd update this for you guys..




















And did some body work....

[F8d2Blk]

That stinks. The truck was looking good.

[C230K]

I better see you in that at the next Vintage Class meet..

[metalmatt47]

Thank you sir! Means a lot coming from a man with some pretty gnarly rides.

Not sure if you remember me, but I actually spoke to you at Import Alliance earlier this year.


I'll be there, as long as I get my 1 piece driveline made by then. Bringing a few other Datsun's with me.

[thesammy]

Nice, love these trucks.

I'm about 100% sure my friend picked up your old wheels, the stock ones. Lol. I saw them FS on that FB group and told him to give you a call.

It was looking real good before the "body work", can't wait to see what's coming

[KeepOnTruckN]

<3 old cars

[shubert]

keep going. looks like its in a good direction.

[l Gizzy l]

Ricer.....

[metalmatt47]

Hey man, how much would you want for? I've been regretting selling my Nismo side draft manifold for a LONG time now. I need side drafts in my life!
