I like it but there's plenty I would want to change back to original. Someone put on a 2 speed wiper motor but coded for 3 speed wipers.

I'm wondering why it's got an automatic but D21 on the tag? 
No wide seam vinyl top, and with a mid April SBD the 340 probably should be corporate blue not orange.
Tread carefully if interested in that one.
