How low can i go?

[1976K5CHALET]

Since the vast majority of my database filed away in my noodle is geared towards 4x4 K5's....i could use some advice. I have a 78 2wd K5 runner that i think i will dig in my box of goodies and swap in an 80 cab with A/C.....but that cab is a 4x4 and i hear the trans humps are different? Would like to clear that up....

Then i am going to rewire it with an 87 up complete tbi harness from a K5 with matching steering column....swap the intake over and add tbi and a 700R4 once i figure out what years of trux or cars can provide a donor 700 with appropriate length tail shaft housing etc.... (member...as carlos says....i'm Deet Da Dee with the 2wd stuff).

So....eventually i want it dumped bad with tucked up 20's or something crazy like a Dub City toy at walmart....but in the mean time....to use her as my shop go gitter....how low can i go with out porterbilts help etc....ie: xx spindles.....rear flip...shackles = xx can run factory rallies....

Smack me with some ideas guys....really wanna start in on this project instead of walking around it in the shop...lol.
