They are here and there. There are probably a few sitting in sheds as spare just in case boxes. I bought a spare some years ago thats done nothing but gather dust since. Funnily enough I got it from canada for $300! It then cost three times that to get it to australia... Still cheap at the time all up.
If you still have the rest of the supra conversion then going to the r154 is a pretty cheap exercise. I did this pathway myself and it was about $500 plus the cost of the box.
It fitted into the LX without tunnel mods other than a small trim of the shifter hole. Unfortunately I dont know of anyone personally who has had one in a LJ.

Yes i still got the complete Supra conversion sitting in the shed, the box is now a spare for my HJ 253 ute with the same.

From what ive read an R154 is possibly stronger than an R33 box but i would probably still have the same problem, no aftermarket manufacturer (that i've found) making a billet slip yoke to suit.

What slip yoke are you using?

What times are you running down the strip?

Do the Toyota tailshafts have replaceable or crimped uni's, the Nissan one's are crimped. Only the VL has replaceable uni's but only small one's.

The Nissan one's can apparently be machined out to accept a replaceable uni but this also took some meat out of the uni cup eye's which i wasn't keen on.

Using standard r154 yoke. It accepts a good size commonly available uni.
I had the tailshaft fitted with the new yoke and it hasnt given a problem since. The shaft was already a custom made goodie and if memory serves correct it was hardy spicer out dandenong way that did the original and the mods for the r154.

My research at the time of upgrading from the old W55 indicated the r154 was probably a fair bit more torque capable than the other options. The nissan boxes were too much trouble anyway with the integral bellhousing. This advice re relative torque capacity was of course from various people in the industry with direct experience. As you have discovered, getting a verifiable torque rating that you can believe is a difficult thing!
The only driveline things that get hurt are the odd clutch pressure plate every 20,000k or so.
The box gets flat changed in anger fairly regularly and hasn't skipped a beat - feels the same as when installed.
Cant complain!

Hmmm

So seeing as your never gunna need your spare box, are you interested in selling it? And do you have a spare slip yoke? PM me.

Did you have a W55 behind the 383? Would have been stretching the friendship abit!

When you say "standard" yoke, is this a Toyota yoke or a Hardy Spicer replacement?

[rexy]

Standard issue toyota yoke.
I will think about parting with the spare box and PM you if you like. I will check to make sure it still has shifter and yoke.
The old 308 killed the supra box back in the late 90's. Pulled all the teeth off 2nd gear as they do.
The R154 outlived the 308 and the 355 that replaced it and has now survived the 383 for a decade.

autogear in syracuse newyork build all new muncie boxes,they do a super case thats a beefed up cassing and a nodular iron midplate to stop the lay shaft driving out the back of the box.the original m22 rockcrushers had a 2.2 to1 first gear meaning you had to run real low diff gear say 3.90 to 4.11 to get off the line with out cooking the clutch with race tyres but they now do a m22w rockcrusher with 2.54 first gear that will work well with 3.5 s and 26" wheels{still do 95 kmh in first at 6500 rpm},these boxes are around 2000 us ill be getting one sent over mid year for the torana.ive ran standard muncies for 10 years with out to many problems,blew my first one up last year putting around 400 rwhp through a locker with r spec race tyres.mind you that was a real early type box built in 1964.some guys in the states are drag racing with these m22w boxes in fullweight chevys, bigblocks on slicks and one guy told me they are rated at 850 foot pound.imho a muncie with a well set up hurst shifter is the quickest shifting full syncro box around.as for super t10s being stronger keep in mind they came about after the high horsepower us muscle cars were all finished and the rockcrusher was dropped due to the fact it wasnt necessary behind 180 horsepower smogger 350s.
