Well never a dull moment in the shop. I did a bit of work yesterday, and this morning. Made the end caps for the boxed in crossmember, welded it together and took about an hour to grind it all smooth. I clamped a piece of 1&1/2" thick wall box tubing to the crossmember and used 4 clamps when welding it to prevent heat distortion.
I also fitted the overflow reservoir. Had to make a riser for it out of 1" square tube so the hose sits nice and level. On the framerail top cap I will likely drill 2 mounting holes, and a couple rosette weld holes and weld up a plate inside the framerail with 2 nuts welded on it for the overflow tank. I also repositioned the lower horn by drilling another tab hole, and flipping the bracket 180°. Then I just loosened the horn mounting nut and rotated the horn so it points downward. I will fill the old hole with weld and grind it down. I did similar with my 67 when mocking up the radiator and overflow tank.
