IRS Diff mounting

The diff I have gone with is a common IRS 7.5 inch Toyota F series diff as found in MA61 Supras, RA65 Celicas and RT142 Coronas.
This diff family is available with an open centre, plate LSD and Torsen LSD in a multitude of ratios from 3.5 to 4.7:1
I used a combination of modified RT142 rear diff mounts and modified front cradle as well as a JZZ30 Soarer rear crossmember mount to securely isolate the diff from the chassis in a strong but serviceable manner.
Driveshafts will be hybrids with F series CVs on the diff side and JZZ30 CVs/axle mount on the hub side.
