I need some help, does anyone know the length of the thermostat housing bolts. I'll be going to pull a part to source bolts from other Mitsubishi's in the yard I was in the process of changing my thermostat because my truck would never reach full temp. While taking the cover off the thermostat both bolt heads broke completely off. I should have known something was up, when my 1/4 to 1/8 adapter broke trying to remove the bolts. Thanks.
