Where do you guys go about getting the black plastic trim to fill in gaps after installing aftermarket stuff?

I currently have a TINY gap between my headunit and the cubby hole in the DIN below it, and I'll also be relocating my digital (adjustable) RPM switch to the lowest DIN pocket in place of the one w/ the door, so I'll need some larger chunks for that as well.

 

I used black foam, stuffed it in the gaps, but you need a foam that isn't very pourus.

 

ABS plastic. They should carry the stuff in a hobby shop. That, or you can try online.

 

Yeah, Parag (nismos14) and I eventually came to that conclusion as well. I'm just not sure how I'm gonna mount this MSD box in the DIN slot securely/where I want it.

Pictures for reference:

 

I got some from Car Domain but they also carry it at Select Products. Use a subfram in the pocket screwed to the sides ot top/bottom to secure the MSD unit and then cut the ABS to fit arround it in the pocket.

 

Yeah, I used black poly/foam weather stripping.
