Rear end width?

[slimjim]

I see you're building a 68, same as me.
well if you haven't already purchased wheels then it will be easy. I am running 19x12s with 325s with the speedtech torque arm and DSE tubs with room to spare for 335s no problem, my WMS to WMS is 53" and the backspace on my wheels is 5.25". If you are yet to buy it all then I highly advise you get the rear end narrowed by speedtech(dutchman) and have it all sent through together.
I thought it would be easier and cheaper to sort the narrowing and third member out myself and it ended costing a lot more than speedtech charge.
