Disc brake purchased

I decided before I invest in rebuilding the engine or beginning this project that I should focus on purchasing all the rarer parts that I am missing. I first purchased the switch-side perch. Next I purchased the carb. And my most recent purchase has been the disc brake unit. All are original parts.

I purchased the complete from Paul B. in Portland, OR. I paid $450 for the unit. $12 for shipping. $6 for shipping insurance. Paul B. is a really good guy and sold it to me for the price he paid for it. May karma come back to him when he hunts down his next rare part! Paul was hesitant to sell it to me. I left the ball in his court after asking him to sell it to me. He responded a few weeks later and offered to sell it to me. California scooterists see these parts sell in the $500-$600 range; although it is rare that they come up.

I posted my request to find the disc brake and buy it on LCUSA's site, but to no avail. The disc itself goes for sale on eBay from time to time, but that seems about it. Stu recommended looking in Scooterist International magazine as they are advertised in it, but Tom G. said the Brits pay crazy money for their scoots and the demand for larger displacement bikes over there would make it a bit challenging to find the part.

There are hydroalic disc brakes and reproductions available. Years ago, when Scomo was still around they sold this repro disc brake (see below). It was sand cast and the quality was said to be so-so. I have also been warned to be very careful with the Indian repros, issues with the quality of metal and I'm not 100% sure, but I think someone once warned me about the safety of them as well (don't quote me).I also read that these repro disc brakes required some work to get it to fit properly.

For more info on this from folks that know a lot more than me, you can read (if you're a member) what the LCUSA members said about disc brakes here.
