Re: 95 LT5 part #
Mike,
Are you talking about the secondary vacuum pump? If so,:
I suspect 90 thru 95 will work.

In this case, your 1992 book provides the correct part number for 1995 also. The vacuum pump was the same for 1991-95 ZR-1 (but, not 1990) and was always available under the original part number. The part number is GM #10098493. It's still available from GM under that number. However, I can't find any Delco parts system availability, so you probably have to get it from a GM dealer. Current GM list is $308.66, but you should be able to buy it for a lot less than that. You definitely don't want to "Buy It Now" for $299.In Appreciation of John HinckleyComment

Re: 95 LT5 part #
thanks verle and joe.theis morning i was foolin with the 41 Willys with LT5 crate motor and discovered my arrangement lacks the vac motor that opens the secondary air ports necessary under WOT and with valet switch turned on.The Willys is a handful without the proper air supply at WOT so will order one of the vac pumps from GM and see if upcoiming autox season even more thrilling. mikeComment
