RA23 to RT142 IRS

[ill-minded]

yeah the vented/non-vented brakes swap over easily

its possible that the soarers have more track.. haven't actually checked it, but its the same type of suspension setup

Well its to late now to go back now got the grinder out

The IRS x member won't clear the tunnel with out mods so the tunnel was made bigger rather than choping the X member.

The coil bases were removed from the old diff and refitted to the IRS
My diff xmember/diff mounts wider than the chaissis rails than the one used by 3t-RA40

I have adjustable inner and outter bushes,these were a bonus on the RT142 IRS not bad $100 for the lot at my local wreckers.

Got loads of pics but my dam net just dies every time i try to host one.

Not to rain on your parade, but really, if you're going to the effort of a conversion like this you may as well fit a better IRS. Semi-trailing arms are pretty historic. Why not something multilink like S13 or R32 rear end?

I understand your point about it being older but my point is it's still being used.
Some where on the forums some one is/was doing an S13 or similar and when I seen the amount of cutting and rebuilding to the body it turned me off it.
I only had to do very limited under body mods and it was in.

The IRS x member won't clear the tunnel with out mods so the tunnel was made bigger rather than choping the X member.

I moded the cross member rather than the car where i could.
Thought this would be better than disturbing the car structure to much.

Yes.

RA60 = solid axle
SA63 = IRS, T-series, drum
RA65 = IRS, F-series, drum.

MA61 = IRS, F-series, disc. Same arms as RT142 IRS, F-series, disc as far as I know, though I don't know if RT1542 got vented. Wilbo66 would know, he has RT142 arms in his MA61, and I have RT142 arms going into my RA65.The brake stuff swaps over anyway...

Don't forget MX73 Cressida. I'm running the diff and vented disc and calipers off one on the RT142 setup.
