t/q = Carter Thermoquad??? I'll take pix tonight. I think I have plenty of room for a spacer, but I was kinda looking forward to using a bigger air filter.
I'll take a picture of that 5/16ths hole, that is my main concern.
like a pike, does it look like this?
I'm probably wrong, but it looks like where the tab of a bracket goes like maybe a return spring brkt. or may have been tapped and used for a A/C application or maybe just a hole from the casting procedure?
