Yes, a dremel tool would work great for enlarging the holes.

 

A hole saw attachment for a drill would make a more even hole than free hand with a dremel. (That's assuming you can find a 60mm size.)

 

I would like to Thank science of speed for offering this product....although there has been many road blocks and detours
I would still like to thank them I am waiting for my product an I am sure i will be happy when I recieve this.....at this point i am sure s.o.s. probably wished they never started this product but I think in the end everyone will be happy! We have a limited production car and it is hard to get any company to make certain products....So any company that does and prices the product at a fair price is OTAY with me!

 

Thanks for the support Italian.

The problem for enlarging the hole, is that the center pilot hole indent that is in the mold for drilling the hole is already removed when you cut the 52mm hole. So, to enlarge it, you have nothing to perfectly center the hole saw or rotozip tool. The best approach I believe would be to outline the hole, then trace it with a very sharp exacto or dremel tool.

I purchased a radio door gauge assembly from Rick Hessel. In it he used Nordskog Street Series Digital gauges. These gauges are 2 1/16" in diameter. Will these gauges also fit the assembly being discussed on this post? If so I would be interested in purchasing. Could you post some pic's please?

Thanks,
Brian
