69 C20 Disc brake conversion issues

[Custom-CAMper]

I have been working on swapping my C20 to disk brakes and have ran across a couple of issues. In this conversion, the spindles sit out farther that the stock drum spindles, and thus the stock 69 tie rods are too short. In the conversion kit I purchased, the tie rods that were included are too long on the drivers side, but are fine on the passenger side. If there a certain length of tie rod that works for this conversion? I am still using the stock drag link.

Also, the new front spindles came with 9/16" wheel studs which do not match the Dana 60 1/2" wheel studs on the read end. Those of you who have done similar conversions, is it a good idea to convert the rear wheel studs to 9/16" so they match? If so, can this be done without machine work on the rear axles?Thanks.
