[68 C10 Driver]

So, one of the things I wanted to solve was what to do with that hole in the firewall that the clutch mechanical linkage went through (First photo). Unfortunately I didn't weld this up before I sprayed the Lizard Skin on the interior of the cab...doing so now would compromise it and I needed to find another way. I looked for firewall grommets large enough to fill it in and provide a weather tight seal from the elements and heat and cold, depending upon the season. Then I stumbled upon a seal that would attach with either screws or rivets, and that is what I went with (photo 2). Once I installed it, from the inside of the cab, I coated the firewall opening with a 3M two-part heavy body seam sealer and then painted it (photo 3). It looks a bit ugly, but I think I will eventually remedy that.
