Adapt a Minolta IV Bellows to a D-200

[IFJOHN]

I have a Minolta Bellows IV that I have used with a Minolta X-700 body. I have purchased a Nikon D-200 and want to adapt to this Bellows. I have not been able to find one and am considering making my own with a Minolta MD rear lens cap attached to a Nikon F mount body cap. Would appreciate any help locating an adapter or comments on my alternative plan.
