Replacement Vents

[Miles Offshore]

Probably won't help but mine are plastic on my 78. I took the ones off the sides of my console and put them on the bow. Not certain if all are the same but the hole that the cover inserts into is smaller than the vent. Since I have plastic I just put the inside part on the bandsaw and removed about 3" on each end for them to work. They are well worn also but at least they were not broke allup like the oter ones. I had some black ones off a 78 formula that are going in the sides of the console. good luck-craig
