drum brakes with LSD?

Never tried it Jeff.
I've heard reports that the Series 1 axleshafts are a tad too long for the LSD diff, or something of that nature. I did have an S2 open diff in my '80 for a whopping month before the engine tried to auto-disassemble. Fit with no problems.

Sorry to sound like a moron, but when it comes to this rearend stuff, I don't fill smart.

I've done several complete disk brake conversion on customers cars. To avoid downtime, be sure to have a custom flex line (SA fitting on one end and FB on the other) pre-made. Im referring to the flex line located in the center of the rear end. Its pretty difficult to find an 1.00 - 1.10 (i think thats what FB is) adapter here in Socal.

So are you saying it might be best for me to look for an '81-'83 small flange drum rear end and located an LSD and do the swap in it instead of the SA style to avoid the wrong type of axel shafts (as peejay mentioned)?
It's going into a GLC, so it's got the the old style thread pitch and needs drum brakes so I won't have to change out the brake master and/or proportioning valve. It also will need to be narrowed and recieve the GLC's mounting hardware.
In other words, I'm looking for suggestions and opinions.

The 81-83 3rd member is a direct swap to a SA. I never had any problem with any of my installs. In fact, in my RX-3, Im using an 3rd member from a 83 GSL with auto tranny.

Im not quite familar on the GLC's brake set up. But, if I were you, I will do the complete disk-to-disk swap to make it unique. To eliminate the brake line issues or to make the install simple, just get a custom made soft line as I mentioned in my prior post. Its cheaper than flaring/install new hard lines with old thread pitch

I wanted to do disk brakes at first, but then I thought of all the other swaps required to make them work (master cyl. etc). I also thought of all the times I've read about racers whom liked their drum rears, but wished they came with an LSD option. Our own peejay is kinda sorta one of them (or does he like open diffs with disks better?).
I know some parts of the GLC came from the RX-3, but not the rear end. peejay says it's around a 6" and 1st gens are 7". It's going to cost at least $500 to do the swap, but probably a lot more.
What if the axle shafts are the same thickness and spline count as 1st gens? That would be great because I could just poke them into the narrowed 7 rear end and not have to have the 7's shortened and resplined.

Closer to 100. If the driveshaft is going about 95, and one tire is going about 50, then the other tire is going (95 - 50 + 95) 140mph.
No I don't.
No I don't.
