Are either or both of these following products equivalent to the above? : AC Delco Axle Lubricant SAE 80W-90 GL-5 10405-1 89021669 and GM Vehicle.Care Axle Lubricant SAE 80W-90 APL GL-5 89021669. If so, are these two products the same as one another? I own a 1987 Morgan Plus 8 with an unobtanium Salisbury LSD rear axle, so I cannot make a mistake in using a successor to 1057721. I want to use the correct product, one of these two or something else, with ACDelco Limited Slip Axle Lubricant Additive 10-4003 88900330. Any knowledgeable guidance would be appreciated!

Here are some screen shots, firstly going back to what GM was using in 1987 in their diffs in trucks and two subsequent supersedes. Enjoy.

GM has the additive. Ford has their's and I'm sure Mopar has one too. Also, check with any parts store. All should work just fine. Be sure you get the right viscosity for your application and you probably want conventional as opposed to synthetic. Couple years ago I did my 67 Chevelle 12-bolt with Valvoline 80W-90 conventional with the GM additive. Prior to that I used Kendall LS lube no additive required. Recently I saw Castrol LS lube at O'Reilly's. Brad PennGrade also makes GL-5 LS fluid. My 04 Silverado came with synthetic so I replaced it with Mobil 1 LS.
