Under front fender vents?

[Valvebounce]

My 620 has three fluted vents behind the front fenders, on the panel where the hinges bolt on.

These seem to me, to be a place where moisture might enter the panelwork. Promoting rust etc. (Although the flutes are canted to discourage it)

What are peoples thoughts about sealing them off?

Picture please. I don't have a flute on my 620 ;)

The vents behind the fender on '76-79 620s serve the same purpose as the pillar vents behind the doors on a '73-75 620.  It's to let moisture OUT of the double-wall cab.  Without the vents, whatever water gets in (and it will, no matter how well  you seal it) rusts the cab from the inside out.

 

However, their purpose usually ended up pointless by the mid 1980s when most 620s started having rocker rust-out, which then allowed more moisture in than the vents could circulate out.

Rocker?

to which part do you refer? I'm not familiar with the US spec lingo.

You know, the "red rocker" aka Sammy Hagar...

 

Rocker panel is the sheet metal under your doors, parallel to the ground. Often rusted through on 620s.

 

What do you call it in NZ?

OH! Are your 620s right hand drive down there?! And are they plentiful?

 

I need someone to sell me a conversion kit/parts for my truck. Maybe a trade? Would you like to be left hand drive?
