N00b question about rear axle

[rincewind23]

Hi all,

I'm kinda getting comfortable now with admitting what I don't know

I finally managed to get the rear wishbones finished. I already had the uprights from Talon, protech shocks and a sierra diff/half shafts from eBay. I put them all together today, and the cases for the CV joints on the half shafts don't fit the apertures on the 10mm plates of the uprights. Is there something I'm missing? I've read the book and searched on the forums but I can't find any info about anything that would hold the outer CV joints level. I can kind of wheel the frame in and out of the garage now, but it's obviously not right.

I've never really worked with this sort of backend before (welding/fabrication fine, engine work fine, but the last car I worked on was a mini so that was all front end), so any suggestions appreciated.

Cheers,
KEv.

P.S. I don't mind answering any questions for info I should have provided but haven't...
