Okay, have a question for all those more knowledgeable than me (pretty much everyone!-Lol!) The ps pump on my 1978 Bobcat 2dr. base wagon went out- 2.3l , btw - and I was looking on ebay for a replacement. the original pump when removed was marked HBC X on the reservoir, but I was curious as to whether or not one marked HBC V would work? any help is appreciated.
