[Oldsguy]

There aren't as many Oldsmobiles and there aren't as many aftermarket parts although there are enough to do most things needed. Parts will cost a little more because of the demand and supply law of economics. The catalogues are basically advertisements and they put their money where it will bring the most return. It doesn't mean that whatever you are looking for isn't available for your engine. Sometimes a call will get you a satisfactory answer. The Chevy engine isn't the same as the Oldsmobile engine or the Ford for that matter, the 350s are diffferent as day and night and parts won't interchange (except maybe the generic 14 inch air cleaner element or something like that). A 1972 Olds Cutlass is an A body car. A Delta or a 98 is a B body car. The Omega is an F body.... I think, I don't know what the toronado is. Oldsmobile engines did not use 4 bolt mains from the factory, didn't need them.
