Looked at what I collected and offer the following findings
Cars found with the single washer built at San Jose during 67 production ranged from approx first of November 1966 through the mid May 1967
Did find one example built near the end of June with the double washers possibly suggesting that San Jose may have had a very late change in their earlier practice but we would need more examples to make that call.
All are unrestored examples and a number of them still have the zip ties installed on the round bumper bracket arm. Pretty much impossible to have removed the brackets and leave the tie in place. A few to share
