Re: The seldom seen 1966 Sport Trim option - a REAL short wideside has been found!
 

So, I do need to get some clarity on the T400 thing....in Chevrolet, the T400 was NOT available even as a special order for a C10 1/2 ton, and I would expect GMC to follow suit for all 1000 series trucks. I was thinking the T400 was a 3/4 ton -up option. Can you or Pete confirm?

So in Chevrolet the T400 was only available in 3/4 ton-up sized trucks in 66' so I would assume same for GMC - not available in a 1/2 ton. Wasn't the truck you sold Clyde a 3/4 ton?

[QUOTE=Funky61;76296]Here is a link previously posted by Ed from Hemmings and that link leads to the auction. The featured truck was a longbed with the Sport trim and a great video link. I’m sure you saw it GMCNUT.

yes! That was a sweet truck someone got. Wonder what happened to the intake and all those parts

GMC 1/2 ton pickups were available in 1966 and later with 400 TH - I think they were actually what was called the 375 which is a 400 TH with a smaller diameter tail shaft.

The attached build sheet for my old '66 (dated 6-6-66 by the way!) lists the transmission as "AT-400 TRANS".

Good question, now that you mention it all the TH400's I have seen in original '66 trucks have been C20's/C1500's. I do think TH400's were available in GMC C1000's with V6's as lizzemiester stated. I'll ask over on the 67-72 Chevy Truck Forum, someone there might know.

Consensus is the TH400 was not available the GMC 1000's (1/2 ton) in 1966.

Must be my lucky day....

I am brand new to the forum and have admired old trucks for as long as I can remember. I decided to by a project truck and found a 66 fleet side with the body in amazing condition. the rust behind the front wheels is the only spot where there is damage. The rest of the truck is super solid including the floorboards and other than some missing trim pieces everything is there...

What I found out today (from you) is that my interior is exactly the custom sport trim package you described. I am excited to know I lucked into a rare option but not sure what that means in terms of value and the direction i should go in restoration.

I guess the one "negative" is that the previous owner put a 500ci Cadillac Eldorado Motor and TH400 transmission.

Like I said I have only been a classic truck owner for about 3 days so I am sure I will have a ton of questions....
