I'm looking at buying a used ERA - what do I need to look out for?

[DrivinWest]

Hey All,

I'm doing my diligence on an ERA with a chassis number in the high 100s and a Jaguar rear end.

I'm wondering what I need to look out for with an ERA of that vintage. I'd also love to find a list of changes that arose over the last few decades. Does anybody know of such a list that shows factory changes at various chassis numbers?

Thanks!
