When I got my 1972 it came with trunk rust, it was 10 years old. My 1974 has a big hole where the trunk should be. But Howard here has a trunk without any holes not designed to be there. I can remember some members here, I think Sir Andy was one talking about drilling or had drilled weep holes to let the moisture out. I’m looking for some direction on location of the holes and what size has worked best. Did you weld tubing to the hole to run it past the heat shield and muffler? Thanks

On the other two probably. Though this car has no rust now, anything designed not to leak will leak. Weep holes at the bottom of an incline just makes sense.

This is a 71 and it does not. Maybe later?

I had a leak around the rear light housings so I drilled a hole on each side and put these in to drain. I've since fixed the hole but in reality the trunk should have a way to drain water.

Oh dude, that's the ticket. Now I just need to know where to put them. Both my other cars had no rust on the sides, it is like from the recovery point brace under the car towards the center. Maybe just buy four and evenly space them across the center section. Thanks

A long time ago, someone actually suggested using a good bead of black silicone bathroom caulk on the tail light housings vs the funky foam seals that we're supposed to use. Seals -way- better and if you have leaks in those areas (most do), its an easy cost effective "one and done" solution.
The weep holes are a good idea! (IMG:style_emoticons/default/beerchug.gif)

Thanks Eric, the stock seals are lacking.

Be careful not to imbed the light housings in sealant, you will never be able to remove them without significant damage. Don't ask

weeps are probably a great idea, or even better, never take her out when it's raining

Not sure about the trunk, but many years ago (35)years I drill extra weep holes on the lowest portion of the hell holes each side. Now 50 years old and still good. Mark

That’s a good idea, Mark.
