It would appear that there were more than one MC for the 1/2 ton truck in 1952? Is there a difference with GMC? When did the MC change? One listed for 47-50 with a 1 inch bore. Another listed for 51 with a 1 and 1/8th inch bore and another listed for 52 to 55 early. It could be you have the wrong kit. Just to make things more confusing, there is also an MC kit listed for get this, 1937 to 1959...? How would one kit fit all three MC's? Now I am confused. This is just one catalog page and it ain't helping.
