I'm putting a Model A on a 32 frame but my subrails are rusty so I am thinking about replacing them. A friend of mine who has built a lot of hot rods throughout the years is recommending that I just do away with the subrails and use square tubing. He said it would be easier to make it fit the 32 frame. The frame has been pinched but I'm concerned with the gaps between the subrails and the frame. I'm not sure how to get the subrails to fit the 32 frame but it seems like a lot of people do it. I've looked at a lot of post on here but I haven't found one that really shows how they are put together with the gaps and everything. I just need advice on the best way to go, either buy new subrails or just use square tubing? Any help would be greatly appreciated.
