quickchange adapters

i've seen these on ebay over the years. they allow the use of ford bells. does someone still make them? do you know who made them? are they still available?

Try Winters p/n 2493 (?)

 

bumping this back to the top. something is messed up with my computer and adobe, i can't view the parts at winters website. can anybody else help?

 

Winters does have them, just put one in my 32 roadster.
Uses, I think, 37-41 Ford bells.

 

...

 

just wondering what the outside dimensions are in relation to say a stock model A rearend, using that setup? also pricey?
thanks
