So, I asked the eBay seller, " ...I have a couple of questions please...1) Do I need to drill anything or remove the coolbox on my GX550? What is the internal size of the space. I am trying to check if my gun fits into the space. Many thanks in advance"
The seller response,
"Dear customer,
Normally, you don't need to drill anything or remove the coolbox during installation.Its size is approximately 7.9 * 5.9 * 3.5 inches."
