working on the smaller vent ball conversion now. the small one is 2 1/4 in tall. it will fit fine on the sides of our dash for the 64-66.
cut out and sanded smooth.
inserted the center piece from one of my casted parts.
compair the original to the new smaller side vent.
next i will cast the new part and send it out for chroming and it will look like a factory 64-66 truck vent but for the side of the dash.
