Very confusing into. That pitman arm is correct for any power steering optioned 1970 Camaro, according to the catalogs. It does not appear to be correct for a manual steering car, but maybe in the early part of the year they did not have all three different types?FlaJunkie said:Anyone else with early 70 Z28's have the 3864881A pitman arm? PS/non-PS?
FlaJunkie said:I am an 02C manual steering and I have never changed the pitman arm. Mine is an 3964881A. Wonder what the letter difference is?
Also wonder what the GMT 1 means? General Motors Tonawanda Plant #1?
I have read that they did have a truck parts foundry...I just never knew much more about it.DCL70 said:GMT - Parts or Accessories stocked at General Motors Truck Division Warehouses.
Did GM have their own foundry that made suspension parts for trucks and cars?
70moneypit said:The early suffix coded "A" version of 3864881 must have been superceded by revision "B" by at least May. Of course, there could have been an overlap in usage of the older "A" and the newer "B", as it could have theoretically taken them a few weeks to use up all the "A"s in the bottom of a bin if "B"s were piled on top of them before the bin was completely empty.
