Big Ford Ends or Brand New 12 Bolt

[barrrf]

Ok, so on my Chevelle I wanted to do CTS-V brakes on the rear. Theyre fixed calipers so Id have to figure out to deal with pad knock back. I thought at first I could just do c-clip eliminators but from what Ive been reading the past few days the c-clip eliminators are more hassle than theyre worth. So the next best option I thought wouldve been to hack off the axle tubes and install the big ford ends - the only problem I have with that is my lack of trust for the local machine shops.

Currently, my car is Hotchkis Rear suspension components. They seem to be fine so Id like to keep them. Also, and this goes against what everyone else would do, I do NOT want to put floating calipers on. So with that in mind -

What would you do? Big Ford Ends on current 12 bolt? Buy new 12 bolt? Something else Im not thinking of?
