1 - The ones with the press in balljoints (includes GH, but probably more too).
2 - RA60 struts will give positive camber. Sigma arms will take it back to about neutral camber. They also need 90mm bolt spacing on the steering arms. And there are no steering arms in this spacing which are as short as AE86 arms (and so therefore I assume TE72 too).
You *should* be able to make them fit with TE72 top perch and spring and strut top. But the spring wont sit in the lower perch that well.
