For helping keep this great
old truck web site
on the Internet for over 30 years! and not clogged down with Ads! Again, thanks! | | | | Joined: Oct 2004 Posts: 10 Junior Member | | Junior Member Joined: Oct 2004 Posts: 10 | I recently purchased a 1955 series 1, chevy half ton and it has a large hole in the top of the dash. It is located about center between the gauges. It appears to have been done at the factory or at least professionally done long ago. I cannot find any pictures of other trucks with this same hole or one with an accessory installed there. I'm new to old trucks and new to this board. I don't know yet how to post a picture here but I can e-mail a couple of pictures if it would help to see it.

I know there are some guys out there with this optionthat can provide you wth pics. | | | | | Joined: Dec 2001 Posts: 1,745 Member | | Member Joined: Dec 2001 Posts: 1,745 | The clock has a housing and only needs some small holes. Your hole must have been owner cut. The only hole on top of the dash would be for the wiper switch.

A large one about the size of a quarter, and two small holes for attachment. I think the larger hole is so the clock light bulb can be changed with out removing the clock.
Hope this helps.

This is typically a dealer-installed option unless the modification was performed by someone else.

I was planning to patch it but then had second thoughts. Figured first I should check with people who knew more about old trucks than I did. I appreciate your help. I'll be reading these boards regularly for information and will probably be asking a lot more questions before I'm through. Thanks Joy for posting the picture.

Just a note about the clock; it is on the shelf in the garage at this time. Works perfectly. It was made by the New Haven Clock and Watch Co. It is truely a large watch. It is mechanical of course, and will run 48 hours on a full winding.
When I first bought my 54, the clock was something I though I would sell off. But have come to like it as well as the visor.
