i think ae86/ke70 strut tops should work as kelway strut braces will fit, ma61 ones work but are rotated about 45 degres, but can be used to gain more caster as well as camber, and s13 f you keen to file the holes out a bit
rack ends maybe..... the rt142 rack is a bit wider than a ke70 but same vintage so it might
what rear end is yours? irs or live axe, irs is f series diff, tough as, i have welded mine had have done almost 20,000 over a year and a bit and some racing/drifting and it hasnt missed a beat except for leaking pinion, most likely from bits of slag ect getting in the seal, 85w-140 has slowed that down thoe. and live axel is t series i think so they should be able to handle a fair flogging too
