Cap is well made, once i cut ( yes drill and cut) the old screws off, i pulled the dist and drilled and tapped the original distributor body, cap fit is tight and thats good. Want watertight!

It was a little tight to fit over distributor but that’s good it helps keeping sparks inside

Rotor button fit good but cap won't fit over the edge of distributor housing. Tried sanding cap to try to fit but was unsuccessful. So going try to contact seller for replacement or refund.Update: added a star. Did get refunded. May had been manfactured defect, i probably could got another kit but had already purchase from somewhere else. Being a boat, dont want problems on the lake.

Doesnt seem to fit exactly as it should and the vent adapter threads were different than the threads in the cap. Had to use a tap and die on the vent to install
