The rotors are the only 1LE hardware I have. They were incredibly difficult to find, and cost about $150 each at the time. Now you can get Chinese knockoffs for a lot less, but you get what you get. I also found the new master cylinder I bought for the conversion. The rotors have light surface rust, but you can still see the original machine marks and it will scrub off after the first couple times you apply the brakes. None of these parts were ever run on the road. The lug studs are metric, M12x1.50. The
B-body and d-body came with 15x7 rims, so your N90s should fit.
There are brand-new Timken wheel bearings packed with Mobil-1 synthetic grease in there. Everything is painted except the calipers. I have High-Temp silver I can apply if you want that. If you want a different color, you can find a range of choices at the parts store. The pads are Wagner severe-duty for Police/Taxi.
Installation is simple. Disconnect the tie rod end and brake hoses at the calipers. Hold the weight of the car plus the coil spring tension by putting your floor jack under the outer end of the lower control arm. Use your tie rod press to pop the ball joints. Swing the upper arm out of the way, install the complete hub rotor assemblies using the same ball joints, swinging the upper in place. Reconnect the tie rod end and brake hose, and bleed the brake fluid.
There is probably $700 worth of new parts plus labor there, but they are not pristine. Make me an offer. PM me a Zip code and I can get you a quote on shipping them to you.
