Have gone to RG fairly regularly, it is a zoo. You simply have to go, and search. The office staff is not of much help. You really can't blame them a lot of their employees are likely making the texas minimum wage which believe is less than $10 an hour. So motivation is not there. They are...

Believe the OP is in search of an aftermarket unit - Edelbrock, Holley, Weiand, etc that had a square bore carb intake, with the bolt holes unique to the '96 to '02 heads.
You should look in el paso, tucson, and albuquerque classifieds. They're still throwing away rock solid examples that are going into the pick a parts down here.
I've got a sale pending on all my setups currently. Am of belief they are all '88 to '94 vintage. PM me if still looking I can see if any new trucks post '94 have arrived, but all the manual setups I've seen recently have been pre '95.
That should be easily pickable at a local U Pull It yard, one would think. There is a "flurry" of those trucks currently at the yard I frequent (several times a month) would be easy to grab one. But again, one would think you could find that easy enough locally. Dave S southern NM
Any resolution to this? Not here frequently, do have three manual setups, some more complete than the others. Really looking to sell as set ups complete.
