I didn't realize GM had changed things so much with the 53. I'm trying to figure out why they made the 3/4 ton lines shorter than the 1/2 ton. Only thing I can think of is routing them the on the other side of the cross-member. Wish I could help on this one.
Any reason why you're not "rolling your own" lines? I'd get inline tube's stainless lines and fittings and bend them myself. It's not that difficult, but it is time consuming.
