Rebuilding Window Regulator

[70 Challenger Lover]

Anyone know if a company that can rebuild the rear window regulator out of my 71 Barracuda convertible? Apparently they reproduce the front regulator but not the rear. Posted a want ad but no luck there either.

Dug out my Challenger regulators and they appear to be identical except that the Challenger crank shafts are a bit longer so I won't be able to use a Challenger one or cobble the crank shaft off of one.

I'm trying to see if one from an A body or B body is the right length because I can find those on eBay all day long and get the part from that source.

If anyone has an A or B body rear window regulator lying around, can you measure the length of the cranking shaft for me? Barracuda ones are about 3 1/16" long so if I can find a suitable replacement, repairing it myself should be easy.
