occ chopper build help!

[MysterySandwich]

...but as far as ive read on mounting you will need some extra length of chain,exhaust and sproket adapter...

Sorry to kind of but-in, it's just I was thinking (debating against a cruiser build) of doing a chopper build... and these seem like hard work.

Just going to ask, where do you get a sprocket adapter for these choppers?
I know I can buy the mounting adapter and exhaust off eBay, and I'm sure the chain can't be too hard to find...?

~EDIT: I just found it http://www.piratecycles1.com/picycbspad.html
Woah.. that's expensive, I think I'm going to just go with the cruiser build haha
