I just found this tidbit in the August 1968 edition of "Chevrolet Service News", and thought it was interesting.
"1967 Camaro Manual Steering Gears Used in 1968 Production"
"In order to use up a surplus of 1967 Camaro manual steering gears, all 1968 Camaros equipped with manual steering built from May 22, 1968 to June 7, 1968 at the Norwood assembly plant [Serial Nos. N438680 through N448071] or from March 29, 1968 to July 23, 1968 at the Los Angeles assembly plant [Serial Nos. L338182 through L359064 (estimated final production serial number)] were built with the 1967 manual steering gears. Units incorporating these gears will also use 1967 steering arms, pitman arm and idler arm. Consequently, whenever it becomes necessary to replace one of the above mentioned affected components on a late built Camaro, check the serial number. If the serial number falls within the ranges given above, verify the existence of 1967 componets using the information given below."
The article then has a chart of part numbers to identify 1967 components.
Steering Gear Assembly....Daub of yellow paint on top
L/H Steering arm.....#3916265 forged on arm
R/H Steering arm.....#3916266 forged on arm
Pitman Arm.....#3908391 forged on arm
Idler Arm.....#3908385 forged on arm
Article continues:
"It should also be noted here that if power steering is installed in the field on a 1968 Camaro having the 1967 components, the pitman arm supplied with the 1968 conversion kit should NOT be used. Instesd use pitman arm, Part No. 3908379."
