building a 9" for a minitubbed 69 Camaro

[roverhybrids]

I just got done mini tubbing the rear of my 69 Camaro project and am about to move on to the rear suspension.
I haven't decided if I'm going to stick with inboarded leafs or go with some sort of link suspension.
I have pretty much decided on the rear tire size 335/35/18's, but I haven't picked out wheels yet.
From what I've read I was thinking around 56" WMS to WMS for the rear.
I have a 9" housing but it looks like it will be about 57.5"
It also appears to have equal length tubes on both sides and I thought that the 9" 3rd had the pinion offset to one side? I don't currently have a 9" 3rd around to measure.
I would like to get the housing and the rear suspension done so I can get the car back to rolling condition ASAP.
I have a jig for narrowing the 9" housings. I also have located a currie built 9" that is around 53" wide.

what to do?
