Warm weather brings updates!
I'm sorry, but I am just not the type to freeze my *** off on something I don't HAVE to finish and then can't exactly paint - well, without bugging my neighbor to use his booth. Beside the point, I really hadn't yet figured out what I was doing for a latch... We'll call that done now. On with the pics!
Here is the bracket setup I came up with. I found this latch off CarParts.com. It's a pretty simple/compact latch that's conveniently yellow-zinc plated. I wasn't thrilled about the play in it, but once you have a sure-enough rigidly mounted pin for it to strike against, it's all good. the other two holes are for some rubber bumpers that cushion the strike and as well take up any rattly play.
Here it is installed, all welded up and latched. It hits like a Mosler safe - so happy with it - zero rattle and you have to drop it from a few inches out to overcome the strike bushings. I wouldn't change a thing. The picture doesn't look like the bushings compress much, but it's actually perfect. I'll also be able to shim them out as they take a set over time. I'm a little worried the latch level might be vulnerable but that's too be seen I guess. I may trim it back or make a guard of sorts. Just relishing in the fact that it works at the moment though; lol.
I'll get some better pictures of everything once it's all painted up. Getting there!!!
