Re: Pitterpat's 84 C20 mild build
 

Mine broke off. I replaced it with a 1\2" bolt . I believe the hole under the nut is only around 1\2" .

Finally got the bolt drilled out; it would have helped if the drill bit had been worth a hoot. As soon as I bought another bit, the "4x stronger (or something like that), it drilled right through. That wasn't all though, I had to basically drill it again to be able to crack it, to pry it away from the rusted threads. Long story short, I got it out and go the hole enlarged for the new nut & bolt I'll be using.

Got a layer of sound deadening down. And that is it today. Will finish the sound deadening tomorrow.

Got the sound deadening finished. And test fit the Amp. I'll look to put something down over the sound deadening.
Not sure why the pics look like this, they are rotated 1/4 to the right in my storage.

Then got the pad and the used rubber mat (I got from junkyard) installed. Used something like really thick landscape material, like 1/16th to 1/8th thick underneath closest to the floor, then the green 1" thick padding, then the rubber mat. Sorry for the dark pictures.

Also, before someone says the mat will be moving under my feet I've got something for that. There was a CB installed on the drivers side of the hump, bolted in to a bracket, I'll be putting the CB back in in the same spot. That will bold the pad down. Then will use the heat gun to fit the rubber mat to the floor.Maybe even use some velcro.

Then I realized I needed something to cover the sound deadening. This truck was the basic WT C-20 truck, only the rubber mat on the forward floor portion and nothing under the seat. I still had the old rubber mat, I took the time to tape it with black Gorilla tape (on the back side) and put it in tonight.

I know it doesn't look the best but I will get it smoothed out; Ill take the heat gun over it and then when I bolt the seats and seat belts back in I'll make holes in the rubber to put the bolts through the rubber.

You see the amp there, I've got to figure out the best place for it since this truck is a manual transmission and has a hight hump than a manual. Kind of makes it hard to mount it flush to the floor under the seat. I'll figure out something.
