Dan,
If the dash wasn't already painted I would take a dremel tool and grind out the slots to make them fit. As it stands now I just got off the phone with Tom Myers and he said he has a pair (apparently for you) and is just waiting for the money. He did tell me about a pair on eBay which I just bid an ungodly sum for; desperate men do desperate things.... Don't know if I'll "win" them or not as there is someone else out there as crazy as I. Ain't that the way auctions go at times?
Its all good though. I may just end up putting the ones I got up on eBay later. Perhaps there will be two crazy bidders out there when I do.
Make sure to get that check out to Tom
