LS1 mounting brackets

[justforfun]

i am using steel plates on a 1st gen fbody & have not machined my spindles yet, but by my measurements show very minimal material will have to be removed from the bottom hole and about an .080" spacer will have to be used on the top. Yes I have to use a spacer on drum spindle unlike others that seem to say they had to machine the top mount. This just points there is a lot of variation in these spindles.

I spent about 2 hours turning my hubs on a lathe, but it had been about 7 years since i had run a lathe. The hardest part was chucking the hubs straight. Machining the OD of the outer ring (outside the studs) was not hard b/c you can set the rotor surface against the chuck. The hard part was the OD of the inner ring (slides through the center of the rotor). In my case this also had to be turned down and there is no great surface to hold.
