I believe AD 3/4 tons came with 15" two piece
wheels or with 17" as an option. 8 lug pattern
should be the same up to late 90's ? when they
went to metric pattern.

Some newer wheels will cause a clearance problem with the front tie rod that you should be careful of because of the offset and width.

You should get plenty of info with a search of the archives as this has been discussed before.
