Yes, they’ll fit with room to spare. If you run the van LCAs 15x7 is as wide as you want to go. Make sure your steering box is beefed up. Area around the box tends to crack. Wide wheels and tires puts a lot of stress in that area.
Here’s a pic of my 74 which I sold recently. I ran cop wheels, 15x7 on the front with 255/60s and 15x10 with 275/60s.
I flipped the axle and replace it with a 8.75, dropped the rear 5 inches. Ran the van LCAs in the fron which dropped it about 3 inches.
Cool thanks! Great tip on frame strengthening around the steering box. This truck already has the van LCA's. So, here is the update for everyone. The truck was delivered to day with wide tires... not the skinny tires in the bay pictures.
The rear tires are 275/60/15. 27" tall and 9" of tread. PERFECTO! The front ires are 245/60/15. 26" tall 8" of tread. The ires that I want to buy for the new 18'x*8" rims are... 255/45/18. 27" tall and 9" of tread. So I have the answer to my original post. Thanks guys!
Now I will attach some pics after I send this reply.
