I'm looking for new blank keys for my 88 comanche. Are they the RA4 or the RA5 keys? (sometimes listed as B46).
I know the door keys are the RA3 type, but I have read conflicting info on the square ignition key. Some say RA4 is compatible through 86, some say only through 84 (but they still list an "84 comanche"). If it works on an 86 comanche, wouldn't it work on an 88? I know in 91 they changed cylinders and adopted the one-key system, but I don't know of any other changes since the first 86 comanches.
