Trying to put my original '68 302 engine back together (has been out of the car for 30 years) and I am trying to come up with the right bolts for the intake manifold. I can see where you would possibly need longer bolts for the lift brackets, smog pump bracket, and the alternator bracket which would leave seven shorter bolts. After going through my old original bolts all I could come up with were three 3/8 16 x 1 1/8 with a "WB" on the bolt head, silver painted heads with orange over spray and three 3/8 x 16 1 1/2 with an "A" on the bolt head, no paint. So it looks like I am missing a few. Does anyone know the correct lengths of the various bolts as well as the correct markings and finish. I have seen several bolt kits advertised but they all seem to have bolts the same length and are silver cad finished. So I thought someone with an original car might know this information. BTW....my car is a third month of July '68 build, late built cars seem to be different sometimes.
One other thing....I have seen questions on the color of the lift brackets and most everyone says they were orange, well mine were painted silver. Anyone have knowledge as to the correct color?
Thanks in advance for any info you can provide.
Well I finally ordered some bolts from AMK Inc. for the intake manifold and here is what I came up with.
10 ea. of 3/8" - 16 x 1 1/4" bright zinc plating with (TR) markings (AMK # B-10137, similar to GM #304722, phosphate or #180124 zinc)
2 ea. of 3/8" - 16 x 1 1/4" flanged bright zinc with (A) markings (AMK # B-10084, similar to GM #3828782 zinc) These two are for the engine lift brackets.
Already received them and they look great.
