I finally have some more pictures to post. I ended up putting a bunch more tacks on the firewall before we pulled it back off the chassis to do the final welding.
Once we got it off the chassis, we turned it up on it's back so that I could do all horizontal welds. This also let me do alot of weld finishing on the bottom of the chassis.
Before anymore welding or grinding.
Here is the firewall all welded in with the transition to the original cowl sheet metal initially finished. A little more touch up and it will be ready for the body man.
These next couple are the new trans tunnel and floor pieces all ground and sanded. Again a little touch up and it will be ready for the body man.
I've been trying very hard to make these welds "disappear", but welding new metal to this old stamped floor pan, firewall, cowl etc. is very difficult. I have been finding that the old metal shrinks and moves much easier than the new. All in all I am happy. it shouldn't take much filler to smooth all this out.
As always any comments or suggestions good or bad are welcome. Thanks for looking!
