Holes in top of dash

New member! 1955 1st. Series What are the two holes on top center of dash? They look like factory threaded holes.

Agreed, post a picture. No factory parts in top center of dash.

Re: Holes in top of dash

that does have a factory look..but I've never seen any like that before..but spacing does look about right for old school c.b. mount..

Re: Holes in top of dash

if that's a c.b. mount some one took some real time making it right. most guys would drill 2 holes & use a nut & bolt. Does look like there is some filler around the hole.

Re: Holes in top of dash

electric windshield wiper motor...The vac motor did not have the two screws through the dash. Your truck would have originally had two big chrome headed phillips screws in those holes.

Rare enough that the majority of us would have never seen one with the screws in place I'd think.

Thank you! That makes sense but how come I can not find another one like this. Was it uncommon?

Re: Holes in top of dash

I just went thru my factory assembly manual and there's no mention of electric wiper.the bracket for the wiper is welded to the underside of the dash and hangs down about 2-3 inches...there's no mention of anything mounting in that area..I wonder if it might be a mount for a dash fan..I've seen many a old grain truck with a dash mounted fan although I don't think they were factory

Re: Holes in top of dash

Correct..but there's no mention in the assembly manual about a electric wiper..is it aftermarket?...I'm wondering what the underside of his dash looks like..in his pic on far left side it looks like the hole for vacuum wiper control knob

That one is VCCA reference truck shot through window showing the chrome head screws.
http://s1295.photobucket.com/user/gr...8zdi9.jpg.html and this is the page from the Factory Assembly Manual showing the electric wiper motor option.

Re: Holes in top of dash

It is a factory option. Fairly rare. Two speed electric motor that uses the same control knob and cable. His looks like the motor must be in place or the threads would not be there. 6V motor. I have a service manual for that wiper motor if needed. The mystery I have been unable to solve is finding a truck with the electric wiper motor and the windshield washer combo. The washer kit had an extra cable from the foot pump to the wiper motor to make the wipers operate when the pump was pressed. The cables worked together and independently. I am sure the motor switch had to have some sort of modification but can find no documentation nor a truck with both options installed and functioning. I have a factory bulletin that eludes to the combination but nothing beyond that.

Re: Holes in top of dash

Thanks everybody for the great help! You are absolutely right it holds the electric wipers motor. If I had reached up in there from underneath I would have figured that out and not wasted everybodies time. I searched all over for dash pics with those holes and could not find any. Thanks again for your knowledge!

Re: Holes in top of dash

For your 55 1st series ( which is essentially a 54 with open driveshaft, different grille accent colors, and slightly different hood side ornaments) you might check Tim Lederman's site. http://www.1954advance-design.com/ Tim is an absolute purist so don't expect any info on a smallblock or adding A/C. But it is a very good source for factory info.
