Wanted-Clam Shell Vents for just a few Clams

[Jim Rester]

Looking for 2 clam shell vents for engine cover.  Would appreciate a lead on a couple or advice.

Would prefer older style with thicker material.  Not modern ones that are so thin you could cut yourself on them and won't stand a little abuse.

Checked Bristol Bronze and $65. ea. plus shipping is more than I think it should cost.

Thanks for your help.
