Well finished up the drum to disk (ls1). just wanted to share with you guys.
I followed the write up in the tech section, wasnt really that hard. I did alittle searching before I did this and the best advice that I found was when drilling the new holes, drill out the bottom two first, then bolt on the backing plate , then drill the top two. In the write up it tells you to c-clamp the backing plate on.
I dont ahve parking brakes yet, but found a few good ides in the search.
Plus I completely pulled the rear out and took my time, plus added a few other parts while I was at it.
Also I never changed my proportioning valve, I have the one for disk, disk. But It works fine, they all lock up. So i figure Iwill try it for awhile and see.
This was the most confusing part,some say you need to change it others say you dont.

Here are a couple picks
