geez dattodude, if you were paying $600-900 you would want the diff to be perfect, you can buy r31 skylines complete for less than that
as it costs all of about $400 to buy a skyline diff and a falcon LSD(both complete diffs)....put them together and you have a second hand skyline LSD and a spare open falcon diff to sell
or maybe wreckers are just nice to me and sell stuff cheap

Fairlanes are the go for the LSD centres.....

I've found them a bit hard to get in the falcons until I discovered nearly all the Fairlanes have them.

EA/EB equivalent Fairlanes...... UC or something they're called.

XRs should all have them

but i guess a big boaty fairlane would be the go as they wouldnt be able to even spin the wheels so the LSD should be all nice and healthy

Speaking off,
I just picked myself one up too. R31 complete disc to disc from a wagon, 4.11 the guy said. $200. Not too shabby. Now to find a fairlane
And about the wreckers being nice to you Pigdog, one of the guys at G's wouldn't stop talking to me about this guy in an orange and black 1200 and how he put a L20b in it. Eventually when I crawled under a Stanza to grab a tailshaft he stopped talking because he couldn't see me any more. Surprised there isn't a picture of you framed by the front door, hehehe

haha yeah brent or bret something like that, he knows roddat on here too, i dont thinks hes even seen my engine though

hes the one guy there that actually knows stuff about datsuns, not as much as me though
