Yeah I have every intention of waiting to see what you come up with as a finished product before I mess with the C body spindles.
I also think I want to retain my current brake set up, so I'm not sure the spindles are going to be something I use. I may look into the A body LCA's though, since at least in a theoretical set up you want to make the LCA's as long as possible. But as you mentioned, that may cause problems with camber. Do you know how much longer the A body LCA's are? Once you have the length it would be pretty easy to figure out the change in camber.
The 1.12" bars I have are 30* offset, like stock. The only 0 offset bars I ever heard of were made by Just Suspension a few years ago, but they stopped making them. I think they were 1.06? Anyway, mine came from Firm Feel and I'm almost positive they have the stock offset. One of the bars was stamped with a "L", but it was only at one end, and as I've mentioned before it must be the end I put in the LCA, since neither visible end is marked. So, yeah, it is possible I messed it up.
I'll find out when I get my new Hotchkis UCA's. I bought a set when Summit had them on sale and I had a discount code, although they're back ordered at the moment. I have subframe connectors to install too, so I'm going to pull the suspension off of it and check the torsion bars. I may also clock the torsion bar anchors 30 degrees to give me a zero offset and return to using stock '73 up spindles. Of course, if it turns out I installed my torsion bars backward I probably won't need to clock the anchors.
