Frank, i put a 55 pumpkin in my 52 panel. No problem and used my axles.
Thanks for letting me know. I'm glad someone has done this successfully.
As with so many other things one step leads to another. Now I have 5 lug 4 3/4" lug pattern on the front and original 6 lug on the rear
I have to find a solution to convert to the Chevy 5 lug pattern on the rear.
More research and a lot more searching on this great forum.
