There you go. I like the way you think.

Good point and I used quite a few nutcerts in the roadster. The one disadvantage is they do not allow the panel to sit all the way flush. I am more concerned about the cowl rigidity than anything. To put a V8 in an old Chevy requires cutting the vertical supports off the firewall. Not good on a convertible with no roof for support. I am going to try to compensate for that when I get out to the firewall body mounts.

Even though the car will not see a lot of moisture, I don't like the idea if water running into the over lapped area either.

John long I really appreciate the input on this guys. It is cool to hear all of the ideas. I went to sleep last night thinking about what I wanted to do here.

I wondered why my convertible did not have a removable trans cover when many of the Chevies did. I think maybe GM did that to increase the rigidity of the convertible cowl section.

Here is what I think I will do. I am going to take my stepping die on my bead roller and "emboss" an area that would be the removable portion of the cover but not cut it out. If the day comes that I need to take the top off I will cut it out with my plasma cutter. I can then make a "lid" for the opening and install it with drill screws, J-nuts, nutserts, or whatever.

Hopefully, this leaves the maximum strength in the cowl and still provides access in the future with a finished look if needed.

I will post pictures for your thoughts.

Can't believe how close your repairs are to finishing the major rust issues! Amazing how much you've gotten done in such a short time!
Just wondering, when you start a project like this, how you decide where to begin? I'd still be looking at it, and trying to figure out what part to start on!

The seam would be plenty far over as you are now. I would make the template wider so it overlaps the pans right to the beads. You can then put nutserts in the pans and have the hump bolt to them and across the front. The back edge will take a little more thought as to ending in front of the crossmember and an additional pan from there back, welded to the crossmember for structural strength, but with a leading edge for the back of the hump to bolt too.

The 4 speeds will fit what you have shaped now easily and the Muncie and Sag are completely interchangeable at a later date. They do take different shifter mounts, however. I "modified" some extra Muncie rods I had here to work with the shifter on the Sag I bought for the GTO. They aren't "elegant" looking, but they work.

I agree. I have had a good Muncie with a new shifter sitting on the shelf for several years looking for a home. My intent is to put it in here. I also have a good Saganaw that I might put in it if I decide the car is for sale. I would hate to see my Muncie go down the road.

Thanks Mitch. You would be right if it was on a usable frame but alas, I still have to pull the frame out from the hardtop and build it.

Not sure how the finances will play into this either. Time will tell.
