thanks for the info..i finished doin my sun visors lol..to be real this is the 3rd time ive done my headliner...ived had it sagg countless times and just took it off...but i finally took the time out to do it right and not rush it..i also used these small pins and placed them in certain areas for extra support just in case...it came out real good....

im gonna start doin some custom carbon fiber pieces my dash and console...and start a diy on that...but thanks for all the pointers and tips man...
