Weld nuts

[Bdhand]

What are people using for weld nuts these days. Let me explain. I am working on a frame off resto and my 66 did not have a back seat but I am adding on and I need to weld something on the underside to be able to screw the rear seat bolts into. I know I can weld a nut on a flat piece of bar but I was kinda wanting to do something that looks a little better than that maybe not stock but close to it. Anybody got any ideas or pics???

Nicely done! Now you just need to stamp some little numbers in the sheet metal part of yours

What size bolts did the seats and seat belts use?

 

[hankjr]

I want to say 3/8-16 for seat and 7/16-20 for seat belts

... There are several companys that sell those like Hank Jr. showed.
I've used a lot of them.

Yes but today I'd go to Fastnal .. I'll have to check the shop but I think the last brand I carried at the parts store was Pioneer ..
& I hate to say but NAPA would have them.
I'm not a big NAPA FAN.. As they came into my town & bought my building from my old land lord .. They walked in & said we bought your building .. GET OUT.
What I'd been there for 20 years. & in another for about 12 after I got it.

Looking at going to get these pretty soon to start welding them on. Are we pretty sure that the seat bolts are 5/16 - 18 and the seat belt bolts are 7/16 - 20????

If you use slightly-newer or modern Ford bolts, they'll self-thread the plates with a drop of oil. Then you only have to drill the correct diameter - you don't have to worry about the actual thread pitch. I've used scraps for weld nuts:
