98EKEX

On my 98 Civic EX coupe, I'd like to find out the thread size and pitch and approximate length of the bolts that retain the power window motor to the window regulator. They appear to be threaded into the motor itself. If need be, I will drill out the heads on the old ones (they arent budging) and then bring the motor with me to match up the size, but I'd love to get the bolts up front than run around. They appear to be maybe 1/2 in long..

Thanks for the help.
