Are those butt welds on the roof sections?
If so, unless you reinforce them the oil can flex is probably going to keep popping that seam.
Do you have a pneumatic panel flanging tool?
They look like this if somebody isn't familiar with them!
You can get them from several sources but, I’ll use the Northern Tool link to give you an idea. I love mine. It has made a big difference in my custom body work! Here's a link to read up on them at.
They allow you to leave a ½” overlap flap by punching in a “Z” in one side. This tool also will punch in the holes for spot welds with a mig welder if you don’t have a dedicated spot welder.
Since you’ve got the sheet metal spot weld with a mig thing down it would be a cinch for you. This flange will give you a stronger seam joint and are well worth the price when you consider you won’t have to redo the butt welds again.
Of course you could weld a reinforcement strip over the under side to the seam to beef it up. But that’s a pain sometimes. But, with the little hole punch part of the tool, it makes it a lot easier.
Looks like the Fiberglass hood will be a lot of work but once you cut it down it may save you some weight. But then again, maybe not so light if you go overboard with the reinforcing on the fiberglass splicing. That part is really fun if you can make the pieces line up where you want them. I like working with fiberglass. It’s so much easier to fudge with.
I think I’d go with cutting down the glass hood, just to keep the “WTF Factor” going.
Love the Grenade Shifter handle. It just says "Road Rage, Mad Max Style"!
