There have been several posts regarding the upper alternator brace on 1967 small block Corvettes. To my knowledge from information received from the (only) three previous owners, this tracing is from the original brace installed at St. Louis on my mid-production run 327/300 A/C Corvette. Images provided here and in the next post are the best I can provide with limitations present. Hopefully, this will help those who have questions or are looking through swap meets for the correct brace.
Bolt information may only be correct for my car but may be a guide for others:
Lower Bolt --- through upper, lower brackets and water pump (in that order) into engine block is a Grade 5, mfr. P, 3/8" dia. with 9/16" hex head. Threads extend approx. 1" and are 16 per inch. Overall length including threads and shank is 1 7/8" long. Cadmium plated. There is a washer but, after removing it twice, I forgot to take notes. Most likely, it is a plain washer.
Upper Bolt --- through star and plain washers, through bracket and into alternator. Bolt is 5/16" dia. with full threads (18 threads/inch.), about 1" long with a 1/2" hex head identified as a recessed head with WB mfr's marking. External tooth washer with flat cut tooth ends and a 7/8" dia. plain washer, approx. 1/16" thick. Cadmium plated.
If these two images are insufficient for you, please email me for my address. Then I would ask you send me a SASE for a full copy (legal size paper). My scanner is for letter size paper only.
Second image to follow.
