Possible SBP to LBP adapter group buy?

Any more than $100 a pair, and you'd be a good share of the way towards a set of Dr. Diff's 7.25 axles with true 5x4.5 bolt pattern and the correct center register; a much better solution.

I'm not a big fan of spacers/adapters either. If you're planning on running a big wheel/tire combo on the rear, you'll need more backspace with the adapters and then when you get a real bbp rear it could be too much and you may need to get different wheels again- negating any potential savings with the "temporary" spacer/adapter solution...
