For sale a '91 MX5 already stripped down. I've lost my garage after a move and a new baby means I don't have the time anymore!
The V5 is included for registration and pretty much everything you would need is there, just apart from the rusty body.

Does it have a LSD?

Looks to be an open diff to me, although I only have the flange ears to make that guess. It would tie in with a British 1.6 of that year. A similar age Eunos may have had a viscous LSD, but that's about as 'limited' as you would have got on standard kit.

Good spot - i missed the picture of the diff & shafts.

I'm up for anything better than the current open diff in our G reg UK car..... It's crap for autosolos.

I don't actually remember spinning a driveshaft to check. but it is an open diff judging by the flanges too.

I'm going off this for a source;
