Yep, anouther newbie bringing up the same question.

Actually, I did a search, and pretty much have gotten most of the answers I need.

Here is the conclusion I came to:
Since there are no Super HiCAS 240's in the yards around here (that I can find), my best bet is the J30.

But here is the thing, my car is an '89 with no ABS. So that means that I have to have my drive shaft shortened by about an inch and being an '89 I have to take the back cover off of my open diff. and put it on the R200V from the J30.

I guess my question is this: If I am correct here, there is no way for me to get a VLSD without having to modify either the drive shaft or the output shafts depending on what VLSD I eventually get. Plus all the aftermarket LSDs that would even be remotely affordable would be anoyingly loud for a daily driver and require fluid changes and regular rebuilds.

Do I make sense? Am I correct in all these statements?

Why does only 89 (or 89/90) require removal and swap of back cover on diff?

Well, I guess all S13/180 type 240's would have to have that done. 2 bolt holes vs 4 as I understand it.

Z32 and J30 LSD's have two bolts on the rear cover, S13/14's have 4.

Swapping the cover only takes a few minutes, it's not hard and while it's off you can drain the fluid. The driveshaft can be sourced from any ABS car, S13 or S14, but do note that this is not always the case. In my car, S14, I kept the OE driveshaft. I also did a friend's S13 the same way. It depends a lot on the play in the driveline, sometimes you need it. the other thing to note is that either an S14 or J30 diff will require the front bushings to put in from that diff also, the S13 does not use bushings and has a much smaller mounting hole. You'll need to fill this on the new diff with a bushing. You'll probably be able to find an ABS driveshaft easier than the diff anyway.

AHA! So, J30 diff, and driveshaft from a 91-93(4) ABS equiped 240? Plus bushings as needed...

Doesn't sound so complicated now.

ACK NO! ONLY the S13 has the 4-bolt diff cover. S14 has two, just like the J30/Z32.
