Wrenchman, Here are a couple of possible resource books I found (all Buick that coincides with your engine) that may be of some use at least in that department. smile

Reproduction 1927 Buick Shop manual w/1928 Supplement

1927 Buick Book of Parts - Series 115

1927 Buick Book of Parts - Series 120 & 128

I also stumbled across this Antique Engine forum that had a thread with several pictures of 1928 GMC T20 restoration work that might have some useful info too. headscratch
