Not sure of D35's, but on 8.8's you generally need a slightly thicker pack. My original shim was about 0.028 and I'm using 0.032 on this one. My Yukons required about 0.034 to 0.036 if I recall correctly -- it was a couple of years ago.
I hope you guess as well as I did, lol. I was blessed to get it right the first time in both cases. I had read about needing to use a thicker pinion shim with high ratio gearsets in 8.8's and so I tried it. I'd be clueless on the D35.
I had to do my D44 a couple of times to get it right.

well got the front set up, had a .050" shim pack and the factory carrier shims, came out perfect, got everything cleaned up and ready to assemble. tomorrow i gotta pass by ford and pic up my pinion seal and the rear shim kit. its not bad once you understand which way you need to shim everything to get a good pattern.
