Swingarm interchangeable?

Can anyone tell me if a swingarm from an 80' ltd 1000 will bolt up to my 77 1000A chassis. I'm wanting to get one to have extended, but I want to keep it near a stock look. I want to make it sort of a sleeper, and with a Kawa unit I can have a fab buddy of mine do the extension, and still retain some of the stocker look and maybe send some people home slackjawed.

yes its the same swingarm,you can pickup about an inch just by sliding your wheel back in the adjusters and running a longer chain if you really want to be stealthy most people dont catch that one!goodluck,happy wrenching!

I think that the swingarms have different mounting brackets for the chainguard but otherwise, should be the same.
