You can use one off any year Fiero with a V6 or a 93-95 Camaro or Firebird with a 3.4 V6. Probably the 89 thru early 90's 3.1 V6 hold downs for the oil pump drive would work, too. The oil pump drive is just a dummy plug without the distributor head on it. I think they all use the same hold down.
Edited to add that I just went out and looked at the hold down on a front wheel drive 88 2.8 V6 and it has the same hold down as a Fiero. I would imagine it's the same as the 3.1's. So probably any V6 Beretta, Cavalier, Cimmaron Cutlass Ciera, Grand Am, S-10 or S-15, El Camino with V6 should be compatible. Maybe even the later 4.3 engines, too.
