Re: Build that 71 402 already

Real trivial here, but I think I figured out how the stove pipes were mounted. This is an early take off set so hasn't been messed with much. At first I thought it took a tap screw from above, but judging by the hole, looks to me it's a bolt inserted from below. A #10-32 bolt fits right in and tightens up on it's own. Add a nut and maybe a lock washer of some sort it's good to go. I have some nice rivet screws with locking star nuts. Should work well:

EDIT: WRONG, my initial thought is right. You can tell by the protrusion on top the stove this took a tap screw. I ended up with #10-32, and a Kep-nut that are black oxide. OT: I like the black oxide on replacement hardware. Nicer appearance than factory zinc phosphate, and black zinc plated too, IMO.

Much of the info. applies to all 67-72 GM trucks, and to a lessor degree all 67-72 GM vehicles. My build thread, and more on the guide https://67-72chevytrucks.com/vboard/...d.php?t=730025
