6 cyl - Did you check you're measurements on that 55 rear? Seems like they are about 62" wide which will put your tire right at the fender. your 37 is probably about 58 - 60 wide. I put an S10 rear in my 39 which is about 59 wide. This gives you a little wiggle room if you put a larger tire on or if you go radial. Of course you can do things with offset rims but they can also change the look.
