Thanks for your replies and advice, guys. I referenced the GM 1108335 part number after reading info from this site:
http://www.wallaceracing.com/starter-numbers.htm
I do see GM 1107355 listed as well. I do not see GM 1108353 until 1968.
I'm hoping that someone here will confirm that GM 1107355 is indeed appropriate for my May 1967 built HO/4 speed (WV code) car. This part number seems to be much easier to find that the others.
Thanks!
