Y Code Parts Dept:1980s Replacement Gauges & Sender Unit Part Nos.

                                                                        By: Patrick Smith

   Those of you seeking GM original NOS (New Old Stock) parts have probably learned by now they're pretty scarce and cost a lot when they do show up.It may cheer you up to learn the Ac Delco replacement parts Division issued a catalog late in 1988 listing some replacement gauge and sender units part numbers alongside their brand new pieces for showroom Fieros, Trans Ams  and older Pontiac 6000 and J2000s. I have taken the trouble of recording these numbers for you and listing them here in case you come across some for sale online at Crag's Lust or evilBay. This way you can compare the list number against what's offered online and decide whether it'll work for you. My only warning is the Ac Delco list was active in 1988 which is  many years ago and the list wasn't updated. Some parts already were no longer in inventory such as the in dash tachometer, speedometer and hood tach assemblies. I have included their part numbers here as a reference in case you see some assemblies offered for sale.In the words of Walt Kelly, creator of Pogo, "We Promise Nothing!"

Notes About the PNs for Instrument Panel Part Numbers
 These were collated during the mid 1990s by Paul Zazarine and Chuck Roberts back when many of the GTO parts weren't being reproduced yet. A lot of external goodies like body panels, interior trim and engine pieces were being done but not crash stuff nor electrical goodies. It was assumed the junk car supply was stable enough to handle this so the part numbers were pulled off existing units. Some panels may have replacement revision numbers stamped there with the older original number cancelled out.
1971  Air Conditioned Instrument Panel 483517
1971 non A/C              Instrument Panel  483516
1972 Air Conditioned Instrument Panel  546619
1972 non A/C              Instrument Panel 546614
 * Early 1972 cars may have 1971 non A/C block off plates which will bear the word "Pontiac" on it. Later 1972 cars will have plain black A/C block off plates. Both types have been observed in the cars.
  

Some early build 1972 GTOs without air had instrument panels with the older 1971 style
"Pontiac" script block off plate. Most 1972 block off plates were plain black. This car was built in December
of 1971. A reproduction instrument panel was installed after gauge clean up and is waiting for the rosewood vinyl transfer.

1971 Instrument Panels used a vinyl film transfer of Castillian Leather. 1972 Instrument panels had vinyl film transfers of Brazilian Rosewood. Both are available as reproductions as are the instrument panels.

Hood & Instrument Cluster Tachometer Accessory #       and Part Numbers:
1971 Hood Tach                                           989919                           pn 5657094 
1971 Inst Cluster Tach                                 na                                   pn 5657064
1972 Hood Tach                                           989919                           na
1972 Inst Cluster Tach                                 na                                   pn 5657922
Note: In 1972 Pontiac stopped installation of hood tachs at the factory. The hood tachs sold were by the dealer and installed either by the dealer or by some aftermarket installer. This is why there is no part number for the 1972 hood tach. Likewise instrument cluster tachs were part of a 3 pod gauge assembly as shown above in the Ac Delco gauge listings and not sold separately.
