I am sure its a stupid question, but how I measure the distance between the triangle of a bike frame in order to properly have a braze on bracket for a rear disc brake. I just got a trek 1989 trek 930, single track and would like to mount the bracket horizontally. Thanks!

There are fixtures for that. I need to put together a list now that Anvil is gone

You can search this forum for ideas on how to do it without a fixture. Basically use a wheel and a brake that you don't mind messing up

Thanks for the info. I think I am going to go from catilever brakes to v-brakes. That way I won't have to spend cash on getting the brackets welded on, the cash it would cost to buy a new wheelset and fork.

That's what I would do and I have everything I need to put a disc mount on there. Also, the paint looks good enough I wouldn't really want to have to refinish it.

I am going to rebuild the bike. Paint it, new BB, maybe a new crankset, Shifters, derailleurs, v-brakes. Quill adapter, some trekking bars and maybe some taller 26" tires. Maybe spiffy up the wheels. I could put new spokes on, however I heard wheel building can be a PITA. The components ware kind of raggety, but I am wondering if they can cleaned up and refurbished. I've been wanting to do a project bike for a while now, and I have one. Apologies for thinking out loud.
