Same here, for 20 years at least. I just put the same one on the BN2, but there's a 'quirk' with the 100 adapters: BN1s use a BSF thread in the block and, supposedly, BN2s use UNF (or whatever the later, standardized thread is). HOWEVER, some BN2s had the BSF threaded block--guess which one yours truly has (required a special order to Moss for the cap screws). My BN2 is a 100M that also used one of the 'oddball' distributors, but it's all original. Now I buy filters in 'bulk' for both cars (and use the same oil, too).
