Rearend question....

JBeryleC · 07-27-2003, 12:39 AM

Can someone one let me know what year Ford began using the IRS setup?

I am looking to buy a 1993 GT Convt. 5 speed
But I do not want IRS.
HELP!

Thank you

IRS didn't start until like 2001 cobra or something. The 93 definately has a solid rear axle.

Ok, great! Thank you.

I have another question too... Is the rearend a 28 spline 8.8" ?
4 lug or 5 lug?
What year did Ford start the 5 lug?

Thank you in advance!!

Yes, 28 spline is factory, the 93 cobra has 5 lug im pretty sure, and the lx's and gt's were 4 lug, until 94+ all came 5 lug.

No, the '93 Cobra is still four-lug!
