NEW GUY {kinda}

I don't think you have enough rear tire! LOL.
Reminds me of my ol' '69 Dart racecar. I had 14x32 slicks stuffed under the rear with stock-height (but lengthened) wheel openings. The car sat much lower than yours and I had to jack the tail waaaay high in the air and disconnect the back of the rear leaf springs in order to pull a rear slick. I don't remember the rearend width but it was short.
Your '67 is looking really sharp!
LoL I have to pull the coil overs and the panhard link ,jack the body way up to get the 33 -21.50's off And couldnt keep the stock tubs so after market tin has to go in but I did manage to keep the back seat you can't tell anythings different while sitting or looking into the car and yeah it's about 3-4" to high the coilover mount was from another project .Im going to make another one 4" lower this weekend and drop the front to match before I have it aligned the housing is 32" end to end~
Oh and 33" tire and 2.76 Gears SUUUUUUUUUUUUCK
Have to get my 5.13's in asap!
