Jeep 4.0 in 69 Barracuda
I’m excited for you! This sounds like it’s finally all coming together! And I’d like some feedback from someone actually rubbing a “truck” trans. Most people just skip that option since they’re not geared like a sports car but i don’t see why it wouldn’t be great on the street.
I have the ranger axle and moved my springs in towards the frame 1/2” per side. I don’t have precise measurements but my wheels are about 11” wide overall with around 7” of backspacing and 4” from the drum to the outside lip of the wheel. I had to trim the quarter well lip and the tires (275) just barely fit with 1/2” of clearance to the leafs, they do rub the inside of the well under cornering. This is on a scamp. You didn’t mention your backspacing but with 9” wheels you should have a little more clearance than me. Unfortunately without precise measurements for your wheels you probably can’t estimate how close they’ll be. I can check to see if they’d fit my car if you get me some measurements, though.
