Been a little while since I posted back in here, so figured I should update. Not having a whole lot of great luck with this install, but I am learning that is for sure.
To fix the clearance issue, I chose not to grind on the eliminator and chose to grind the heads down to .200, which I felt was safe, and removed the thick lock washer and used a star lock washer instead. This had plenty of clearance, and the elims pressed on the axles. Of course, my 12 ton Harbor Freight press had to be reinforced twice and there was a lot of welding, cutting, and metal replacing. Spent about as much time "re-fabbing" the press as I did in the rest of the install. But, I wanted to get my $ out of that press I bought off Craigslist for cheap and not pay someone else to press them on...
So, after pressing them on, drilling and clearancing the brake backing plates, etc it was ready to install. I boneheaded it up though installing the backing plates, axles with c-clip elims, etc on, torqueing them down, etc before I realized the wheel cylinder needs to be reattached to the backing plate BEFORE putting the axles back in... So, back apart it went to install the cylinders. Got them in, got the brakes all back together, got the drums on (of which one needes the holes opened up to clear the 1/2" studs) and was test fitting my Superlites with 275/60's on them. Fit well, so I was excited.
But... when I was spinning the lug nuts on, they started snugging down but when I pulled the deep socket back I realized the lug nuts we NOT tightened all the way to the wheels, but were tight! Got all the lug nuts off but two, and those two were so galded up they would not go on or off any more. I ended up having to use a long pipe and break the studs off so I could get the wheels off and fix the now broken studs. Of course this meant taking the brakes back off, alxe out, backing plate off, etc, all back down to bare axle housing. Come to find out my cheap lug nuts from Summit were not threaded very well. You could see halfway through the lug nut (on the brand new ones) where the thread got a little sketchy. I had to run a 1/2"-20 tap down them a few times to clean up the threads. Tested them after tapping them and they work fine now. OF course, I am now waiting for a new set of studs and lug nuts from Summit, then will have to grind the heads down on 2 bolts, then put it all back together...
I think I will do a "how to" (or more realistically a "how NOT to") on Moser C-Clips elim install. I took pics of it pretty much the whole way. We shall see...
