Thread: Fitting a JAG IRS to a AR-110 International Pick Up

Tweet

Guys

Graham from Perth, Australia (Perth is on the West Coast) here.

I am fitting a Jag series II front end and IRS to my AR-110 International pick up and I am after ideas on the best way to fit the IRS.

I have fitted the front end using the original mounting points but the IRS is a bit harder. I would like to leave the IRS in the cage but the AR-110 chassis is too narrow to make good use of the four IRS cage mounting points.

Is it best to
1. Make a new cage assy to fit the AR-110 chassis
2. Weld crossmembers and plates etc to support the diff centre
3. Make brackets and try to use the existing cage mounting points

I have attached a jpg showing the relationship between the cage mounting points and the chassis.

All ideas and comments are appreciated

Graham, my first suggestion would be to fasten the rear end with something more substantial than baling wire. Okay, enough sick humor.l

You could trim back the cage to allow it to fit within the rails, being sure to add gussets at the attachment points to avoid torsional twist. Alternately, chuck the cage and fab the mounting points out of flat and tube stock. Of course you want to make sure you maintain the geometry, and shock mounting points both for angle and travel length. The advantage to either method, but moreso the latter, is that you can set ride heigth. Don't know if you intend the get the truck close to the ground as it should be, but Jag rears entail more effort to do that. You may end up C'ing the frame rails to allow sufficient axle travel depending on how low you go. Also, shedding the cage will make it somewhat easier to service the rear calipers if necessary later on.

Thanks for the reply - the baling wire does work loose hence the need for a more permanent arrangement.

I think I will go with fabricating a suitable frame as you suggest

Well guys I have finally done some work - the chassis is finished and the body is getting closer to being finished

Some very fine work!!!! The suspension worked out great, should make a very nice Hot Rod when you get it finished.... When the work comes out that nice, the amount of time involved doesn't really matter!!!!!!

Thanks for the kind comments Dave - this project has been a lot harder than when I restored my 1926 Chrysler Tourer!

Looks like some nice progress G man. Nice to have someone come back after time and give us an update.

I have included a couple more photos to show the Pontiac style taillights that I am fitting and the flattened firewall.

Other specs for the ute (pickup) are a 5 litre GM V8 stroked to 6 litres coupled to a 4L60e auto tranny that has been tricked to provide firm gear changes. Along with the Jaguar suspension the rear trailing arms are a combination of Ford Falcon and Holden Commodore bits, the master cylinder is from a an XB Falcon and a Holden Gemini (Izuzu) 7" brake booster. The front shock absorbers are from a Datsun 720 ute and the steering column is from a Ford Fairlane. The doors will be shaved and I have ordered an Elite series airconditioner from RJays. Hopefully the A/C will arrive soon (it has been over two months since I ordered it), and once fitted, I can concentrate on the other odd things like handbrake setup etc

I still have a long way to go but am getting there slowly

G,day Graham.
Cant belive there is another AR110 owner on here and also in Perth.
Your Inter is lookink great.
