Tires - yeah, they'll fit. You may rub a tiny bit on the radius arms, but with 15x10s the chances of that are slim to none.
Bed - The bed will bolt right on if the new truck is a short bed. Fuel filler necks are different, bumpers are different. But that's about it really
Thanks Sean, I really appreciate the info. It seems I have a decision to make concerning my truck. I have an '82 f150 stepside, 4wd, 300 and a 4spd. Yesterday I found a deal on craigslist on an '86 f150 fleetside, 2wd, 302 w/ automatic in (almost) identical condition as my truck. I've always wanted a stepside V8 street rod, so I'm considering buying the '86 and swapping out the parts I wanna keep from my '82 to the '86 and selling the '82. I'm just having a hard time giving up my transfer case,..ya know?..lol. I don't really "need" it, but I just like knowing it's there if/when I do need it.
Anyone ever heard of a 4wd street rod? Maybe this question should be my next post..lol.
Thanks again man,
