Ok I understand all about the Gran sport In my family there is a 65 skylark gs convt w/4speed, the riv 4 1970 gs stage 1 cars, 1 gsx w/4speed, 2 1974 gs 455 ,a 68 calif gs, 68 gs400, 69 gs400, 72 gs stage1, 70 gs350, and about 50 other vintage buicks. These are all origanal cars and all are matching #s . So just the pic shows that it has a single 4 carb does not mean I dont have the 2x4 set up that goes on the power plant and it has the turbo 400 switch pitch tranny and the correct posi rear. It is missing a few interior parts yes but is a real riv gs not a clone or wanna be. I'm the 3rd owner of this machine but in all one has to have a starting price and I really dont want to get rid of it but some times you cant keep all you have . Thanks for the information it was needed
