Which 3.55 rear are you looking at? Or was that just a number for discussion purposes?
I have a separate thread where I was asking about swapping a '57 center section into my '36 housing. Turns out that's not possible, but before I knew that, I found a '57 center section with 3.55 gears for sale, as well as one with 3.90's. That's why I was asking for opinions on ratios.
I also have a Ford 9" rear here and a 3.50 center section that I could use. I had that rear end for a different project that was never used. It's a posi and 31 spline. A bit overkill for the 235, plus I'd have to buy new 6 lug axles to use it, so I'm looking into other options instead.
