I was told this was a 92. And I believed him. Went ahead and bought it. Suspension was bad so I bought a nice rebuilt shock off ebay for that year. Got the suspension out and here the lower rear mount is a bearing as well as the top. So it must be a 90 or something. The frame number is missing so assume I'm in for some trouble. Dont be an idiot like me haha.

 

I came to the conclusion it's a 1990. Could I throw a '91-'92 swinger on a 90 frame without issues?
