10, wow! Didn't realize there were that many. Still, bet there isn't one that will bolt up to a 235.
How about a NV4500. Heavy duty trans, and the case can be drilled to match your 235 bellhousing. I drilled one to fit a 69 bellhousing, behind a 250, then scrapped the idea, due to the elctronic speedo drive. Didn't want to tear the trans down, and convert to mechanical.
