1968 Cowl Plenum Install

[RamAirBirds]

I am currently putting back what i assumed to be a "owner installed" cowl plenum back onto my 68 Z28. Have the correct A/C and what appears to be a modified firewall duct...possibly from a Chevelle. This was done way way back in the day and so it needs to go back on. I bought the last made boot a member here had that is correctly seamed together on the bottom. I am curious on both where you got your boot AND are you going to put the factory staples back in place on the AC side. That is the last hurdle I have to do...I have heard they used both Round and Square staples (similar to a box staple). My original Air Cleaner clearly had small "round" holes so this is what i am going to use. I am thinking that the staple used for putting the flaps on the front wheel wells should work. Just curious what you are thinking of doing if anything.

My boot was purchased from a friend who makes them. The rubber is a little thicker. Which keeps the assembly more secure, and the boot doesn't collapse like others. The seam is made of the correct burlap type material. You could smear/sprinkle some baby powder or the like on the rubber for a show display. To get a more realistic visual of an old one. I don't know if he is making more or if he has any in stock. I will check with him and send you a PM. Note: He also has a guy that makes the top lids. From a copy of his original. They are fiberglass. That is what I have. I am looking for an original top. He doesn't come to these sites. And I am not sure he wants his info offered. I will have to check with him.

I jumped on it a couple times during test drive. And the boot pulled away from the air cleaner side about an inch on the front half. So probably going to follow the holes and punch through the rubber. I have a friend in SSF that has a bunch of staples connected to old rusty front ends. I am going to beg him to pull some for me. He doesn't know it yet.

I think you are correct, probably the same staples. I thought there was a build thread here or another site, maybe Chick's BY car, that showed someone buying the wire stock and cutting, sharpening and making their own. But I can't find that link. I'll be in touch... Danny

Great results! looks great. Man that setup is rare. Have to ask, is that smog equipment bypassed? Looks like its all functional.

Really nice to hear there is a performance difference. That had to be fun.
