91 Dually wheels specs

[chicknnhead]

I have an old 76 dodge motorhome, last year i removed the old 16.5 coined wheels and got a set of 6 16" steel coined wheels off a 91 from a member of this board. Anyway for give me for not measuring but everything is cover in snow at the moment. but i was wondering what the specs are for 91 dually wheels. maybe there is a FAQ that list the back spacing off set is, what the hub hole is.
it seems a year later i want to order a custom set of wheels, and these wheels specs might lead me to the correct wheel

i know it seems crazy for custom wheels on an old motorhome, but it's my little project hobby.

So much for thinking I could get rid of some 16.5 rims!

wow can't believe it's been 4 years and I haven't completed this project.

I guess life gets in the way sometime
