one for the diff/brake experts -

1 .... are all the rear drum assemblies on the 1200's (h145, h150, h165 ???) excluding piston dia the same ?? drum diam, brake shoes, back plates etc ??
or do they vary depending on axel size ??
2 .... did the trx bluey come out with an lsd factory fitted ?? or as a factory fitted option ??

any input would be appreciated cheers in advance

h145 and h165 drums are diffrent completely, dunno bout h150 but would assume diffrent to both aswell

trx's did not come with lsd's
except about 500 government issued blueys, so extremely rare, though i have known one person to find one in a wrecker
