Also, it needs to be cut down on one side to center the pinion. Not going that route at this time. Also remember, this is a 70's Mazda, which means NARROW. Hell, a GSL-SE axle is about 1.5" wider on each side than the Cosmo, and an 8.8 would be another 1" over that.

So GSL-SE with 5 lug it is.

You can use the GSL axles and brake brackets. It will narrow it about an inch overall than the stock GSL-SE. I actually had Moser shorten and machine the bearing seats another 1/2" outward to shorten mine up enough for what I was doing, had to make my own brake brackets though. Still had more than sufficient room on the stock axle tubes to install discs. Overall I'm probably about 2" narrower than the stock GSL-SE track width (1" per side) was when I got it. Even this would leave you about 1/2" wider per side. There is enough room to machine and shorten the axles another quarter inch or so per side, but it would be pushing it to go much beyond that and would probably require shortening of the axle tubes.
