4 link help

[ozman3803]

Having troubles finding info on 4 link. Application is on a 70 c-10 swb, I want to run air ride with a pretty fat tire, not laying frame but want a decent drop with just c-notch. This is a street application with a dream of someday a big block w/ 6spd. Can somebody tell me pros and cons of 4 link parallel vs. 4 link triangular. Some links with pics are always helpful and what ever info you guys can provide. I saw some of the Captain Fab's work but that was about only thing I could find (great but want some more info). Art Morrison kit could be a option, but additional options would be great. Also doesn't sound like panhard bar is not the best, looking at Watts Link...any suggestions?
