For Sale 1 of 101- 72 Stage1 4 speed

    BUQUICK I'm your huckleberry.

    Larry that is great info! Thanks for posting it as I think this puts to rest any question about it being correct for not only your car, but for ALL 4-speeds. Notice that Richie posted above that his car was sold new in Colorado, not California, and yet it also has an EGR valve. His signature says it's a 4-speed as well. I just took a look through the assembly manual but I couldn't find any mention of the applications for the EGR. It just shows how to route the line.

    So it would appear that a 4-speed car gets the EGR included at no cost as part of the 4-speed and will not have E5 on the window sticker or Sloan documents. But an automatic transmission car built for sale in California would have to pay ~$15 extra. So what if a 4-speed car is built for sale in California? Free EGR or pay $15? :) Which also makes me wonder, why does a 4-speed car need an EGR valve and an automatic doesn't? We will probably never know why.

    I bet that the GS455 4-speed carb is also original to your car since all else appears to be unmodified under the hood and the date code lines up correctly.

    Sorry to get your ad off track but I learned some good info from your car and research today. Thanks. Good luck with the sale. It will be interesting to see what the buyer of your car decides to do with it, just make it run & drive or restore. Either way it would be cool to see it. I know I'd like to have it.

    This is a great project and being a stage 1 4 speed matching numbers car worth all the effort.:)

    Man, I love this car. I'd love a factory Stage 1 4-speed to go with my replica. Unfortunately, the currency exchange hurts me too much. GLWS.

    Is there any crunchiness under the vinyl top?

    I don't think so but I'll look again and verify.

    I’ve read that modern engineers have a difficult time setting up the emissions software for manual trans cars because the transition from open throttle and load to closed throttle/no load is one of the most likely to generate excess pollution. I doubt they were that precise in ‘72 but maybe the carb tuning for the manual was richer?

    Here are a couple of pictures of the vinyl top at the rear corners of the top. Found a couple of spots on the passenger side that have bubbled up but don't feel soft. HTH

    Did this car trade hands Larry?

    No, I still have it. I have had some interest in it but nothing solid yet.

    Larry, in the future I would avoid saying "nothing solid" in any for sale thread, LOL :D

    Yes, that comment could be misinterpreted. LOL.

    I do have an individual that continues to be interested in the car. It's just a slow process.
