Im running a custom set of 15inch chasers on my 1200 ute with datsun centre caps. picked them up from a few different wreckers here in syd to make up a set. there a spare rim from a old skyline with steel mags and a 15inch chaser in the boot the best thing is the offset allows a 205 tyre on the back (with no spacers) and std datsun stud pattern to boot.

If you can't find any, the other chasers i seen are from the old pintara there datsun stud pattern too, but only in 14inch. still looks nice and fat and available everywhere cheap too.
goodluck
