I bought mine from king springs. Good quality. Expensive. Used 75mm ones too fit the diff housing and they did need trimming. And where m10 so didn't have too drill the backing plate. The #OOPS#ty lowering block kits use imperial I think so needs too drill the backing plate out. And the u bolts stretch alot. Can't ever seem too get a firm tension. The kings spring u bolts where High tensile so didn't stretch alot and tensioned up well.
Chris I'm in no rush mate. I'll pay in full and you send it too me whenever it suits you. We are taking advantage of your skills and time. If it becomes a pain for you, you may not won't too do it ever again.
I used autoking. call kalil 0423627648. he did my coupe. just ensure your window washer and wipers work. tail lights headlights hazards. all the essential simple things. handbrake too. he understands that the cars not perfect and the tierod end rubbers could be cracked for example. but he does check the essentails. hope that helps. he is mobile as well.
worst thing for me is someone making out like my datsun is a lump of #OOPS# or picking out the imperfections i love about datsuns. Kalil is good like that but dont let him down with a car thats not safe on the road.
