I have a 1957 Rambler with a 196 motor. I am putting in new rod and main bearings. (motor still in car). Can anyone tell me what bearings size I need? Part # on rod is AM # 3125965 With a DME. Main AM # is 3126217 ,also a DME on it. I assume these are std. size, as USUALLY there is a .10 or .20 or .30 stamped on them. BUT you never know with a Nash. Any help appreciated. Also, where is the best place to find these. Thanx, Al
