Thank you guys, the links are much appreciated.
My kids and I built a 66 gmc together. And now we are building “the Batmobile” as they are calling it. So I will definitely be sending one of them into the trunk to try the latch. The previous owner somewhere along the lines “tubbed” and rounded out the rear wheel wells to fit drag radials so we definitely have our work cut out for us. Overall the car seems healthy and mostly rust free. Has a SBC 350 instead of the Buick. But we are on the hunt for another big block or if we are lucky a buick 350
