Hi there,
I also have a "new" IRS box - built by Paul @ Bears Motorsport
Single Side Cover IRS casing
Super Diff
3.88 R&P with stock gears
Welded 3rd + 4th
Chromoly mainshaft (for racing)
HD side plate + clutch arm
New bearings
Steel shift forks etc. etc.
- I built it for my old Ghia that ran a turbo motor on 24" tyres for the street and strip - motor made 207 rwhp
cheers,
James
