An LD-340 manifold will take a standard Mopar T-stat housing, Unless it has been modified. Two bolt holes on either side of the housing is correct, I think the bolts are 3/8, or 7/16 in. It sounds like one of the bolt holes has a repair to it. It could be a Heli-coil. The heli-coil should be tight,so as to hold the bolt good. Make sure it is and also make sure the T-stat housing face on the manifold is flat, use a steel rule for a straight edge,if it needs fileing, leave the surface a little rough so as to hold the gasket better, but make sure it is flat.
An LD-340 is a good maniflod, wish they still made them.

Good idea to use studs on the thermostat housing. You can pull the threads easily with bolts in aluminum. Being that one hole has a repair in it already. IMHO. Good luck. Terry.
