I am lucky in that I have all the SP-1 carriers I need but I don't think that you will have a lot of problems with temper. M60Joe does carrier conversions on a mill and it might be worth it to send him a brand new carrier.
As fr converting a lower to use it with the link... personally, I would just buy a Bushmaster that will work right out of the box but that might be just me...
I am curious how hard it would be to use a standard drill press and carbide cutters to lower that shelf by .2" and also mill out the sides a little for the Link. I could do the sides w/a dremel since there is not much to cut away.
That would be hard on a drill press as they are not made to handle the lateral pressure like a milling machine but it is just an aluminum alloy so it might not kill your drill press?
It seems that most good gunsmiths would have a mill to do this so I would hire it out if it were me if I really didn't want to just buy another receiver. Then again, if you mess the receiver up it's not like it is that much money to replace it.
Good Luck!

Welcome back, it's pretty quiet these days since we were taken down by waves of spammers. That part seems to have been fixed, we had a LOT of cleanup to do, but we are spam free now.
