There's nothing wrong with Amalie -- it's good stuff. Here are the specifications for the Jag/Salisbury differentials that ERA uses (in both the Jag inboard and ERA outboard braked flavors):

The filler and drain plugs are ½” square. Fill to about ½” below the bottom of the hole with Moroso climbing gear lube, SAE 90, part number 34800, mixed with 4 to 8 oz. of Amalie limited slip additive (part # 505-6775). If the above are not available, you may use 80W-90 GL5 lubricant with an equivalent limited slip additive. If the limited slip seems to be sticking (ratcheting around sharp corners), drain add refill, replacing the Amalie additive with 2 tubes of GM additive 1052358.

Where did you find this?

Ratcheting of the rear used to have its own section in the super-secret part of the site reserved for owners only and lubrication details were outlined there. The last time I accidentally posted a direct link to that area Bob P. came by my house and threw rocks at my windows (broke two of them, in fact). But, as luck would have it, that info is also included in the "free version" of the ERA manual that is available to all. Click here: Download instructions for the manuals and web site and then click on the Free Assembly Manual for the 427 to download it (it's in PDF format). Then go to page 150 and you'll find it there, along with the capacities and suggested lubricants for transmissions as well (like the Toploader). I don't know what the true viscosities of any of the recommended stuff is, but I wouldn't second guess the manual since Jag based rears have been used exclusively in ERA cars for the last thirty years or so.

Very good, thank you. I love that ERA site. I have found a lot of great info their in the past
Their info for the tranny goes against what I have heard about Toploaser do's and dont's...specifically GL-5 and synthetic being OK

I found GL4 at NAPA about 2 years ago. Haven't read all of this thread but if you are looking for a source for GL4 check there.

[davids2toys]

I will check it out, thanks

I called NAPA yesterday and pick some up today, I don't know if this is the one you are talking about. It is called STA-LUBE and is made by CRC.
Multi-Purp[ose HYPOID SAE 85w-90 GEAR OIL.
API/GL-4
Part # SL24229
This was the only stuff that was pure GL-4. I am not sold on using it yet, but I grabbed it because they only had two bottles. I can always return it. Even the weight was weird, 85w90, hmmmmmmm.
They had the REDLINE MT-90 right next to it...I was tempted, but the synthetic is suppose to be NG. I guess I will just get more knowledgeable and then finally make my decision.

also thinking about this.
AMSOIL - Synthetic Manual Transmission and Transaxle Gear Lube 75W-90 (MTG)

Well, I don't know the answer to that either. I have a TKO600; but if I had a Toploader, I would probably just ring up David Kee and then do whatever it was that he told me to do....
