Has anyone done this swap? I tried searching but couldn't find it, sorry if this is redundant.

I remember talking to someone a few years back who said that he did the swap but didn't change the proportioning valve and he "didn't have any issues with braking". I realize going from Drum to Disc you would need to change the valve, but was wondering if anyone has done this swap and what you did/didn't do, what worked, didn't work.

This is actually for my 79 Corona, which is identical to a Celica Coupe rear end, but I figure the Celica swap would be more popular.

Any info much appreciated. I have the diff, just picked up a LSD, have new calipers/rotors, all the handbrake lever/cables, brake hardware, etc.

Thanks....

I would think in your case, the only thing I would worry about is the width. I am in the process of getting a rear out of a MkI supra myself. but it is for my 76 Celica, so no help there. I would think that since you share the same chassis, there should be no issues other than the aforementioned proportioning valve issue that you are already aware of. I plan to pull the valve from the MkI I am getting the rear from.
Most likely, you have not heard or found anything about the swap, because the corona is not as popular as say the AE86.

No, I haven't ever heard of anyone doing the swap with a Corona, but I know it's been done with a Celica. I have parts microfiche for all my cars, and 1st thru 3rd gen Celica, so I'm able to look up all parts and check the interchange. I know that the rear end will fit without a problem, the housing is the same as the Celica Coupe (there's a rear diff cover like the Coupes, not a front drop out third member like the Supra and liftbacks)

I've done all the research on what will work and what won't, just wanted to find someone who's done it to see if they did change the valve or not, and if so how they went about it.

Incidentally, there's two threaded bosses on the left apron of the Corona where the Supra proportioning valve could mount, and when I got the Supra valve I got the front and rear brake line that comes from the master cylinder. It all fits! I checked it this weekend and it's so weird that there's a spot to bolt in the valve, and that the two factory Supra brake lines can be used. It makes it so easy. I would just have to plumb the brake lines after the proportioning valve.

If you're going to attempt the same swap, don't forget to get the e-brake cables, you will need them. I go the whole handbrake lever and everything in between just in case, and glad I did!

For calipers, I got them from Toyota as a reman part many years ago. I don't know if they still sell them, but when I got them I had a friend at a dealership so my cost was relatively cheap. Here's the part numbers if you want them:
47730-14111-84
47750-14111-84
47730-14121-84
47750-14121-84

if it is a 79 to 81 supra the rear end will bolt into tt132 lift back coronas or any 5 link corona around from 77to 81 model as they shared the same floor pan with the ra40 series and the same shirts as well
