Want I want is to put a b20E distributor on a b23. It's a long story why, ...but I need to.

So, I thought to drive it I'd use a b20 oil pump drive shaft dropped in the rear position like a b20 OHV. Yeah it would spin the other way, but that's Ok.

Nope. Won't work: gears are bevelled the other way. At first I thought it was because of the auxilary shaft turning the opposite way to the way the cam in a b20 does. Not really, because the front gear on the aux shaft is bevelled the correction direction (and no, front-of-block is not an option.)

My two optiona are to take a b20 and b23 oil pump drive to a machine shop and have the b23 one modified & an adaptor made to duplicate the function of the b20 one (as in the collar to drive the b20 distributor), or

*find someone who has a b21/23/230 oil pump drive with the collar on top*

Hopefully with the off center cuts to drive a ditributor, but anything is better than this one where the shaft doesn't even come up flush to the top of the gear.

I have reason to believe such a thing exists. It will look like a b20 oil pump drive, but be identified from the top (as it would sit in the engine) as having the gears go down toward the right (clockwise).
I'm not sure where it would be used, but may be in early b21's as a vestigal thing. I dunno, that's why I'm asking.

Anyone, anyone, Bueller? (jk)

Do you want photos?
