I have a 1965 Buick Skylark Convertible that is very perplexing: Wildcat 375 motor (340) with a 4 speed manual. I can't find any evidence that one could exist in 1965 since the 340 didn't show up until 1966. I am taking pics of the VIN and cowl tag tomorrow but I was curious if anyone has heard of such a beast? It appears to have been Astro Blue with Ivory buckets. It doesn't appear as if there is a stub where an auto trans would be on the column. The 4 speed actually looks correct (not the hurst shifter). The engine looks to be of the same vintage as the rest of the car and look very correct (though the air cleaner inlet tube doesn't EXACTLY match). Also has air conditioning but other than that I don't know all the options. So, it is in very rough shape, been sitting years and needs a LOT of work - probably a parts donor car and a lot of work to get it in decent shape. It was purchased over 25 years ago by my uncle on a used car lot.
