Changing Stud pattern

[jesus_is_alright]

Hey guys, i know one of the ways to change the stud pattern on the front is to do a disc conversion, but i think even though i'm gonna be runnin 15" on the front, the hoppers kit may be too big (and expensive)
so is there an easy way to change to HQ pattern and retain the current drums? cheply and legally?

I think there is to much meat in the bedford hubs to drill down to holden

best bet for you guys in OZ is to find someone with the HQ kit on their van, take the adapter to a machine shop and get X amount made up, then find an engineer to machine the discs to suit the bearing already being used in the original kit then you can share/sell them around
