Acclaim wheels on an A-body?

Well I am not going to say no way since Chrysler has done odd things over the years but considering every other fastener on a Caravan is metric I can't see why they would not be metric on the wheels. Also the early Caravans had 5 on 100mm, it was not un common to see people mounting Dyatona Alumium wheels on them.

FWIW, my 97 Avenger had 5 on 115mm wheels.
