what bags and cupmounts for a 75 C10

[full foot notch]

alright, im planning to bag a 1975 Chevy C10 SWB that im about to buy, and im somewhat unfamiliar with the 2wd Chevy stuff, so i was wondering, with a fullsize 2wd, do i use a 2500 bag or a 2600 bag,cause since its 2wd it would tend to make me believe to use 2500, but since its a fullsize would it be better to go with the 2600, and can i use bag cupmounts made for the S10 with the C10, cuase i found a site that had blueprints for S10 cup mounts, or do i need to use cup mounts made for a 1500 series pickup, of course im going to use a 3 inch drop spindle with the setup, and is it worth it to get the DJM tube control arms that are lowered cup mounts, cuase i was hearing that if you use the spindle and control arm drop setup, that the control arm cup is going to hit the ground when trying to spark

sorry if there is any confusion

or if someone could show me pictures of how the front is setup, possibly thier airbag setup in the front

and out back im going for a 12 or 16 inch notch, so im most likely gonna run a 3600 bag outback, now thats gonna be fun to do
