Distributor engine type

I am trying to sell stuff and in my pile I have a box of distributors. I been out of mopar scene for a long time and don't remember how to tell, sb, bb, rbb. I actually posted a mallory on here for sale. Thanks guys

Just want to list them properly on here

Mopar Distributor Shaft Lengths

Also note the orientation of the vacuum cannister
B/RB:

A/LA:

This is due to small blocks and big blocks having opposite distributor rotations.

Thanks that makes sense. What if no vac advance, like the mallory I'm trying to sell?

Then go by the shaft lengths as listed in the link I posted.

As in which pic is correct place to measure from?

Small block and rb is close to same size depending on how you measure, any insight is welcomed. This is what I'm selling I think it's for say a 440. But not sure

Looks like an RB distributor- 413, 426, 440.

Thanks. So would make it for a 440. Is what I'm thinking. Thanks a ton. Jim
