A/C compressor clutch relay

I've looked for specific parts for all 3 or our Oldsmobile's on CO, and managed to always get what I needed. So. Here I go again: Need the A/C compressor clutch relay that is mounted on the right front (passenger) fender lip about 1/2 way toward the front of the car (1968 Olds Cutlass FlatTop Wagon, by the way). It has an external resistor, wire wound, mounted on it. Must control the A/C clutch. Have 12.6 volts going in, about 11.3 coming out, and my shop owner/friend/fixer-upper says that's too much voltage drop. He strongly suspects bad external resistor. Said if we knew the resistor value, he could replace "that only", but wouldn't look as good as the factory unit. Anyone have a spare one laying around, or know a P/N and where it can be ordered? So ready for this dual unit A/C system to work for more than 100 miles, in the summer, on a 2000 mile trip to the OCA Nationals!!!!!
THANKS!
Aron

I have an NOS unit that I will sell. It's a 68 only part and very hard to find. If you're interested,I'll dig it out for you.

Be most interested, IF it is the correct one with the wire-round external resistor.......sorry, the car's in the shop, and I can't run out and look at it........my memory isn't quite as good as it used to be.

If I can find it it's a NOS GM part and I think it's still in the box. I bought it for a car we did,a 68 442 Conv. and the guy wanted to use his old one.

SB is in the shop being worked on, so can't run out to look but would say it looks right. DAMN! Seems excessive in price, may have to fabricate something. Thanks for the lead.

I have $75 in the one I have and I do have it. It's GM part # 401700 and it's NOS in the original box.
