Got some weird shaped stuff in my firewall i'd like to plug/run wires through.

One of which is probably... a 2.5" x 1.25" oval-y hole. Anyone have a source for such things?

 

Rubber Bumpers I'm sure you might find something that works browsing this website.

 

Yeah i spent a couple hours on there yesterday...

I bet i can figure out something that WORKS in a pinch from there, maybe, but it's complicated a bit by needing to pass wire through them and have them seal.

Two ovals above the steering rack.

 

Make them yourself with rubber mat/sheet and some goo?

Or just a lot of cables, rubber edge and goo.

 

I have backup plans in place. I'm just looking for a source for what i asked about, specifically.

I know they have to exist, this car had them. NLA through mazda.
