    Default 70 gs 455 with ac not shown in sloan build options

    I have a 70 gs 455 convertible. The car has AC and all the components look original GM. However, the Sloan papers do not show that my car had the AC option. What gives? Was it added later? Maybe a mistake by Sloan? How else can you tell if it's original to the car?

    Could of been converted to an A/C car. Its been done. The opening/ cutouts in the firewall are way different though. If the Sloan says it didn't have it, Id lean to that as being correct.

    Without removing the heater box to look for welding scars, or without finding the build sheet in the car, Im not really sure how you could verify it independent from the Sloan or POBF

    Oh and welcome to V8Buick! Be sure and introduce yourself.

    What you could do is open the trunk and find the date codes on the trunk filler panel and quarter panels. They're stamped in the trunk channel area. For example, my 72 GS's quarters are stamped "044" which is the 44th week. Now compare that date code to the production date on the trim tag and make sure they are within the right dates

    That would be a piece of the puzzle in determining weather the car was converted or possibly re-bodied with an A/C tub.

    Might be worth going back to Sloan and asking them if they could check the records again to see if a mistake was made. I remember having this car checked out several owners ago, when it was for sale back in 2004.

    Could so be a mistake from the factory and Buick never invoiced the dealer for the option, and it hence it wouldn't show up on the report. These things did happen - I have a car that tbe D99 Painted top wasn't invoiced, but it's on the trim tag. I could be wrong, but I thought Sloan could provide a copy of the original order form too. I've seen examples & assumed that's where they came from.
