Lets not worry too much about the "why", looking to see if anyone has any experience with it....
In my 87, Ive got a freshened up 2.6l running a weber and a jerry cam, larger 2.6 clutch, through the MSG5 and 8/10 bolt axle combo (Soon to be 10/12, saving up for my front Lokka) on 33s. The 1.87 Low range just isnt low enough. My first thought was swap an MUA5 in, and go for the revo gears, but thats alot of money for not so much reduction. Certainly better, but id like more. Basing off my dads 2.8 trooper on 31s with the 2.26 low range, I feel that needs more too. Also, MUA trannies are scarce and expensive in Canada (Been quoted $400 and $450 on the 2 Ive found) and with covid border closures, no crossing the line for one. Which has led me to the doubler option.......
I see on the MUAs you can run a T case from an auto behind the MUA case, can you do that with the MSG as well? I see the MSG is slip yoke and all of the doublers I see use fixed yoke cases. But the casing on the MSG is steel/cast iron or something, which could be easier to attach the mounting plate for the auto case and close up the MSG case after lobbing off the front output. Although welding cast iron doesnt always go well either....
Just going through my options i suppose, I have one last line for an MUA I have to check out, an older fellow has a trooper on the side of his barn that he has let me pull parts from before. Havent been by in a few years, but I plan soon to take a drive and see if he still has it...
Cheers!
