Has anyone ever gotten grief from tech when drilling and tapping the stock bell housing to hold small clamps or brackets? I know at one time I had heard you couldn't bore those 2 large (3"-4") cooling h0les like the early air cooled glides had...

If it is not a SFI cert case it should not matter

If it's a stock glide housing 67TSCHEVY2 is correct it doesn't matter BUT if it's a SFI Certified housing I've been told you can't drill h0les for lift handles or additional cooling. You might call Reid Monday morning: (925) 935-3025 and ask them.
