I can let you know in the morning if no one else gets back to you.
I'm assuming chain and belt driven are the same.
It's the typical mitsubishi bolt pattern which I thikn is 1.25 if I remember right. I think its ,m8 1.25 pitch or is it 1.0 pitch. I cant remember at the moment.
Take a fender bolt off the inside of the engine bay and it should screw in, then you can get an idea. They are maybe a half inch deep with lock washer.
