[Travis Miller]

1964 Thunderbolts racing today in NHRA Stock and Super Stock are allowed an aluminum or steel front bumper but NOT fiberglass. The fiberglass front bumper that came on a few of the early production cars was only allowed in AFX. That ruling made by NHRA in 1964 is still in affect today.

Of the original 100 Thunderbolts produced, most had the front bumper mounted up against the grille. That was accomplished by tabs welded to the stock bumper brackets that raised the bumper.
