You may well be right, Gert, but the coil in the car is the original,and it has been in there for forty-two years and well over 200k miles. The replacement I found is only ;-) 36 years old and from a car that rusted out after only 86k miles -- that's Maine for you. So I feel pretty optimistic that it will last a while. Now, if Danny is right, and the cables in the 122s are shorter than the ones in the PV, I'll be up the creek, but only out of 15 bucks. There's a good chance I'll survive that. My tape measure tells me that they are about the same length, but I won't know for sure till I have them lying side by side on my bench. At any rate, I'll keep the old coil and generic switch in my trunk, along with the spare water pump, fuel pump, fan belt, and all the other good stuff one shouldn't leave home without. I will also keep looking for a handsomer after-market switch, although all the vintage Volvos with replacement ignition switches I've seen so far have the same ugly glob on the dash that I have.
