I got a set of these for my 88 b2. Get them from SummitRacing for around $40-$45 a pop. DOnt go to 4wheelparts they sell them for $90 and say they are made by PRoComp (crap company) .. They are Actually Cragar's that ProComp tries to brand and call there own. I got the 15x8 with 4 inch offset.
I also have Fiberglass front and rear fenders. They fit nice inside the fenders and add a tad more width which is nice. I bought these and replaced the stock 15x7 rims that came on my bronc's. It is an Eddie Bauer edition, so it had the american eagle look alike rims with small holes. I have BFG AT 32x11.50x15 mounted to them.
I actually wish i would have stuck with a 7 inch wide rim and aluminum. They are steel and very strong, but weight 10 pounds a piece more then the stock rims whish were 18 pounds. It made my tires a tad bit shorter and a tad bit wider. I was getting 23 mpg and now i get 20 mpg because of the 40 pounds extra weight at the rotation. They are also somewhat stiff compared to the aluminum rims. I got the black ones and are very nice, but with the added weight and being 1 inch wider, you will notice the difference in mpg, and you will notice the acceleration and braking alot.
Want to buy mine? lol. I got them a few months ago and have been on the street the entire time..
