Rear Hair Pins or 4 link?

[Big Dirty]

I'm building a 31 Ford 5 window on a Gary Dagle '32 pinched rail frame. I have a set of hair pins for the front but cannot seem to find anyone who makes them for the rear. If I can't seem to locate hairpins for the rear I'll need to decide between running a 4-link w/ a panard bar or a Triangulated 4 link.

Any info on where to locate hairpins for the rear would be great otherwise information on the difference between the 4 link and the tri-angulated 4 link would help alot!!

Thanks- DIRTY
