Stop in for a cup of coffee
As always, little surprises along the way.
For some reason this casting's mounting holes were a couple hairs under 1/2".
Fortunately found a couple reamers in the landlord's pile. Saved me trip back to the house.
Then back to the fun part.
Slip the header into the bay just so.
Install the steering box and start the inner bolts.
Go underneath, hold header out of the way and finish with the steering gear's mounting bolts.
Position the header just so, and apply thin coat of high temp rtv sealer around the ports.
Hang header on front stud. Jamb light between header and heads so it doesn't touch the ports.
Go underneath and pull the rear tubes over the rear stud.
Back up top, Start front bolt with combo wrench 1/4 turn at a time working the header front in. Install and tighten the rest of the bolts, then the end nuts. Torque. Coulda been worse.
