Satisfied with the new custom look our Big 10 was taking on, we progressed to addressing some of the maintenance issues that had cropped up. One of the questions that sometimes pops up when a group of guys are talking about old trucks is what determines how long a factory original part will last, wear or time. In the case of our Big 10, we'd definitely say wear had nothing to do with it, but rather our electrical components were more like a time bomb. With only 75,000 original miles on the odometer, the Big 10's switches seemed crisp, but the A/C fan-speed switch had a direct short in the high position, and the inoperative headlights were caused by a fried dimmer switch. Once again, Classic Industries was the source for genuine General Motors parts new in the box. The chrome four-way fan switch was a direct replacement, as was the aftermarket dimmer switch manufactured for Classic Industries by Wells of Fond Du Lac, Wisconsin.
In addition to the repairs that required the replacement of new parts, there were a couple of repairs we made that didn't cost us a dime, and after we finished restoring some of the Big 10's original features, our old Chevy was a lot more fun to drive.CCT
We noted how the brackets were positioned on the original bumper before we transferred them to the new chrome bumper. |

Provided the original stainless steel carriage bolts are in reuseable condition, they can be polished on a bench polisher to a high luster as brilliant as chrome and then reused (before and after viewed from bottom to top). |
All that was necessary to remove the original grille was to turn the mounting screws counterclockwise and then jiggle it out of place. Installing the new Classic grille was a simple reversal of the process, making sure not to overtighten the screws. |

Removal consisted of unbolting three righthand threaded 1/20-inch bolts. |
