cheap i.r.s?

Somthing to keep in mind. The RX7 rear ends get alot of negative toe when they are all the way down. If you plan on driving low in the rear i would get a rearend that has A arms instead of a trailing arm like the RX7

damn lol there goes that idea for an rx7...any other ideas?

supra is the same pattern as rangers

so is cobra which is same as tbird,but a tbird has a smaller bolt pattern

Correct.......Mark VIII, T-bird, and Cobra are all essentially the same center chunk. Cobra has a lil different A-Arm setup than the t bird and mark viii.........the mark viii and t bird both have a 5x4.25 bolt circle and the cobra has the 5x4.5....however it is relativley easy to have the hubs of the mark viii or t-bird redrilled...thats what i did.....also the t bird is a cast center chunk and both the mark viii and cobra are aluminum.......IMO these are the best IRS to go with.....i myself have the mark viii and my bro is using a t bird on his ranger......they are similar to a front suspension and have a long arm short arm setup on them....they are easy to narrow and you will only get camber change throughout the articulation whereas previously stated the RX-7, 300ZX, and similar rearends with a single trailing arm caster alot when at full articulation.....i got my whole rear cradle from a 93 mark viii from u pull and pay in orlando for $99........they have locations all over th estates....there site is www.upullandpay.com

check my 03 4runner profile for some pics of a basic mark viii irs setup

u can get cobra hubs and have them mounted to the t-bird rearend or lincoln. just a second option to redrilling them

cool thanks guys...any pics?

ya you could do that...but cobra hubs arent cheap.....and i paid $50 to have my hubs drilled....cobra hubs are at a minimum $90 a piece.......my brother paid $100 to have his redrilled so i would say having them redrillled would cost between 50-100 and be a lot chepaer than the cobra hubs

i have a mark viii sittin on my trailer with a customers frame im about to be building ill probably get some pics up durring the build.

a Mazda 929 has an IRS and is about the same width as a mini, and has a 5 bolt pattern thats the same as a Ford. plus the center carrier has an aluminum finned cover.
