Battery hold down bolts
« on: September 28, 2016, 12:36:25 AM »
I got some original 67 battery hold down bolts. In comparing them with the AMK replacements you can see the replacements are 5/16 longer. At a MCA judges meeting Bob Gains had one of his original Autolite batteries. We sat it next to the current reproduction and noted the reproduction was about 5/16 shorter. If you compare a original battery tray with a reproduction you can see that the cuts for the J bolts are higher. All of this can add up to 3/4 of an inch extra bolt thread.

67-69 are 8 and 5/16  1970 are 8 5/8 because of fatter plastic hold down in 1970. All of the service ones and AMK's are the 8 5/8 . it is a little bit of a trick to cut them off to the correct length and bevel the edge to look like original. Ed Meyer has made some up with the correct length and correct beveled end and sells them on ebay.
