LMC and 90-91 Crew cabs?

[kevinr1970]

I am trying to order some parts for my new-to-me '91 GMC crew cab.
Looking and the LMC catalog, they only list to '89 for most parts, and some only to '87.
Is this a qwirk with LMC, or is there something so different on a '90-91 (square body) crew that I am looking for into a black hole for parts???

I tried to call their 1-800 number, but they person (with no truck knowledge what-so-ever) gave me the canned responce of "if it isn't listed for my year, it is available". Also told me that they do not have any tech help available...

For right now, I am specificly looking for fuel tank filler hoses, that go from the gas door to the tank (32-3306, 32-3307), and the turn signal lever w/cruise and w/wiper delay (34-0785).
(both hoses have holes cut into them to I assume syphon the gas?)
