I'm putting together a Panhead from cobbled parts, and here I have my rear wheel. I haven't been able to find one that looks just like it, so I'm not sure what axle spacer I will need to get the brake backing plate the correct distance from the drum, and also correct distance from the axle plate (unknown hardtail frame).

Ive included pics of the hub/brakes. If I had a positive ID on them, I'd know which year axle spacer to get.

Also- when you guys build rear wheel setups on a custom chopper, do you have these spacers custom made to line up the sprockets? Seems like a complicated part to have manufactured.

Here are some of the varieties I've found. At $50 a piece, I can't afford to buy em all and resell what I don't need. I also can't find measurements for any of them, so measuring my setup doesn't help me unless I get it custom made (seems unnecessary).

Definitely explains why an image search for big twin drums turned up nothing similar.

Now I'm thinking I should run one spacer inside the backing plate/drum to get the right gap there, and another outside the backing plate to the axle plate. Varying the size of the exterior spacer would allow me to get the sprocket right where I need it in relation to the trans. Anything wrong with using two separate spacers to get it all rigged?

Yeah, fuck that mess. What exactly is "BT type"? Am I gonna be able to use the sportster wheel and just source a new brake? I'm not running a front brake (at least initially), so it's gotta be adequate in the back.

Big twin. So can I mount a BT sprocket/brake on a sportster hub, or am I starting from scratch?

Where would I be without you guys. So I'm looking for something like this... I'm just gonna get a complete setup, so at least I know the parts to look for if theyre buggered:

Cool. I think I'm sorted. Time to hit the swap meets.
