Projects quick change using model a banjo question

Ive seen them and cant find them but the quick change center that uses the axle tubes and gears from your model a banjo it replaces just the center section?
anyone know where I can find them and also it sounds like it may be alittle weak and I should go with a full quick change setup has anyone used these?

 

its being powered by a stock 8ba if that helps

 

I've got a Kiwi Quick change in mine, seems to work well.

Halibrand nade a Model A quick change plus a V-8. The Model A was similar to the stock center section in that the pinion gear was supported only at the pinion shaft bearing. The V-8 model followed Ford design by incorporating a "straddle mount" which had an additional bearing inside the case. They both were designed to use stock axle trumpets and axles. I see the Model As at swap meets now and then-I believe they were often used in Midgets.

 

There is a Model a QC and a midget QC....the change gears are different....The Model A QC is hard find, a Halibrand that is..Kiwi is a good one

 

Rodsville should do the trick for you.

 

I've seen a model a one at Hershey...not seen the kiwi one in person but have heard good things...the model a rears are a little weak behind flatheads but ive seen them work too...it's a toss up
