70 GMC Disc Conversion / Rally

[dboboltz]

All,

I apologize in advance for this question. I have read all threads that I can find on this subject and I want to make sure I get it right - this is a $1,400 project.

I have a 1970 GMC (6lug) step side that I will be converting to 6 lug disc brakes (no drop). My truck currently has steelies with dog dishes - looking to convert to period correct Rallys and new tires.

#1 - I am looking at 6 lug 15x8 with 3 5/8" backspace rally wheels for sale locally. Will these clear the front disc when converted? Other options, or is this the correct wheel to purchase?

#2 - I am looking at 255/70 BF Goodrich Radial T/A's - with this wheel/tire combination clear as needed and not hang outside the fenders?

Pics of my truck if that will help with my questions.

Any thoughts would be appreciated. Thanks in advance

Dan
