just get a sheet of ABS plastic and cut out the rectangle and then your circles, done
i made my single DIN gauge thingy for the top mount thing in the center where the extra compartment used to be and it fits and looks great. and i dont have great dremel skills either.
but if you arent the DIY kind of person i saw someone selling these in the private classifieds of iclub. i think they wanted like 80 bucks or somethin. too much if you ask me considering ABS is pretty damn cheap (maybe it was made out of something other than ABS?). plus you dont get the satisfaction of DIY
and you are not limited to ABS although that does match the interior very well.
If you are referring to Derres Catalano's gauge masks (which run just over $70 shipped), then I've got one and they aren't ABS plastic. They are anodized billet aluminum (though, since they are flat black, they do look plastic...hehe). (NOTE: You can ordered them with clear anodizing also which gives them a polished silver look instead.)
$70 bucks is still probably a little steep for a gauge mask, but if you don't want to go DIY, it's about your only choice unless you get a full pod. Also the quality of these gauge masks are absolutely amazing (since they are billet, there are no welds and thus they look very smooth).
also to point out. i do sell custom made guage pods that convert the top storage pocket into a guage pod, without loosing the storage capabilities. i have done several using the autometer 2 1/16th guages, but can build them to hold anjy guage that you want. price is a bit more than most. at $125 per pod, but no one else makes one like it.
I made a single DIN 3 2-1/16"gauge mounting plate for my car. My first attempt was with plexi, don't waste your time on this. Once you cut the 3 2-1/16" hole there is very little material left and it gets very flimsy. This will happen with most any plastic. I bought a piece of 3/8" aluminum plate from www.onlinemetals.com for ~$4. Had I metal working tools it would have been an easy piece to custom fab, as it was I took a measured drawing to a machine shop and for ~$35 they cut it to fit, bored the three holes to the exact size and location, and they dipped it in a black anodizing bath. I am very happy with the results.
