Need a picture of a 53 3100 pass side defrost vent. I can not get my new glove box to fit as it hits the defrost vent.My pot metal vent points straight down and searches don't turn up pictures only SMILE.

There are many different types of these vents, the correct vent could be steel or pot material by 1953 and point toward the firewall. I believe the straight drop vents were used beginning in 1954 which may explain the problem.

Brad's bent defroster inlet vents look like vents shown in the 1953 and 1954 truck heater installation instructions. They are angled (not straight) and the diameters of the inlet holes are different.

The hose-inlet on those vents are directed towards the firewall, as shown in this 1951 installation manual for air flow heater and also shown here for recirculating heater.

The smaller diameter vent goes on the passenger side.

Brad,

Do you know if anyone sells reproduction spring clips (one is used on each inlet vent)?

Thanks,

Tim,

I have not seen those clips reproduced as of yet. Maybe someone will catch the thread that has seen them somewhere?

Thank you Brad and Tim. My 53 has the bottom one in Brad's post. I will post in the wanted forum for a vent.

Tim:

My truck did not have defroster vents, so I found a pair of cast metal vents via Ebay. But, they did not have the clips so I simply used small machine screws and bolted the vents to the dash (using existing holes). However, I do have one of those clips in my fastener bucket and have no idea where it came from or if I will ever use it during restoration.
