XJ6 ifs/irs

Dang, I need to read more closely. Did you do a Jag swap on the front, too? I'm pretty confident that the 232 will run well but I am looking at swapping in the Jag engine if possible.

I haven't used the Jag front suspension, but have talked to a few hot rodders who have used it in other cars. They don't mention any issues once you get it installed.

The late Jag IRS has outboard brakes that are easier to service, but mounts totally different than the 61-89 XJ6 type. The "new" one came out in 1986 for the XJ40, but the XJ6 Series 3 continued to use the older type for a few more years. It shouldn't be hard to mount the newer type in another car, just not as easy as the old. Main reason is the old type was designed specifically to fit where a live axle used to be. The newer type was designed for a specific body. I don't know about track width on the newer type. New type has a crossmember that bolts to the front of the differential (instead of on top) and mounts low on the body, about even with the driveshaft hub on the pinion shaft front to back, about even with the bottom of the differential top to bottom. There are two strut rods that mount to the body at the rear. The big problem is the springs and shocks. Instead of four only two coil over shocks are used (saves some cost there!), but they have specific mounts on the body. You'd have to make a crossmember for the upper coil over support.  Wouldn't be hard to do, and new longer rear struts would probably use the old shock mount points just fine. Look at my post on mounting the older type -- just 8 pieces of 4"x6" flat plate and a few bolts and you're in!

Of course, having the parts on hand and actually tearing into the car to change everything out is relative to how well the stock parts are functioning once I get my hands on the Rambler. This may all be null and void if what's there is perfectly fine, and I may be putting some Jag stuff up for sale!
