No, all the pick up points for the control arms are in the wrong spots, and the diff is wider than the RA28 item. If you force it in there, your bushings will bind on the points, bolts, and body.

sean try a mx23 rear end but you will still have to cut off the pickup points from the T series to put onto the Fseries

MX13/23 diff is 1410mm across. Too wide.

Get a Toyota Crown MS112 diff and cut it down (cheap as chips and common as dirt). Weld RA28 suspension points to it (do a comparison - it may be very similar - I don't know as I have never looked). Redrill axles and rotors to 4 stud. Put an MA61 LSD centre into it. Custom handbrake cable. This diff runs beautiful (and frightfully expensive) dual race axle bearings just like your RA45 one.

Lighter than a Hilux diff, better than a Bog Warmer limo and of equal strength to your RA45 diff. I used one in my Corona Mk2 and have converted it to ventilated discs but still using the standard (slightly modified) calipers. Should you desire, it is easy to get out to a 300mm rotor still using the internal drum handbrake. I have some pics I could email to you of the ventilated brake conversion if you choose to go down this path.

MS112 diff is 1410mm across.

Not if you already have some very shiny expensive wheels to suit a 4 stud pattern. Smile

But if you have bling a T series would be fine Razz
