Bolt size for rear seat loop 71 Chall?

[Songsrme]

I'm not having lucking going back and forth to hardware store.....The skinny loops that hold down the rear seat back. I've seen crazy sizes out of AI....and can't find vendors advertising them, but they wouldn't advertise the size any way. Anyone know what size/style bolt goes in there? Thanks!!

The screws to secure the bottom of the rear seat back frame to the floor brackets are 1/4"-14 x 7/8" with a 7/8" washer and 7/16" hex head. The following image shows the screws:

Thank you very much. I appreciate that.

This is sort of an optional fastener, because the seat bottom holds the upright in place. Several cars I've worked with over the years are missing these screws.

And if those aren't in place, the seat back rides up about another inch when you put the rear seat in. At least on mine. Looks weird through the rear window. Thanks again. At some point, after I work through issues, I plan on posting some info on this car. Interesting story. Car was partially restored by GYC...let's just say they aren't the end all in restoration! Lots of missing stuff, or incorrectly routed stuff, etc. Anyway, it's a cool car. 71 V code Chall 4 sp dana car.

oh, good point. I wonder if that issue results with restored interiors, because in the examples I'm thinking of, the seat covers were cracking and/or worn.

My 73 had screws that were flanged. They did not hold well and the threads stripped when tightening. So I used some spare fenders u-nuts with bolts to hold the upper rear seat down. Much better holding power and no slipping of the "u" from the upper rear seat. You probably have some spares lying around.

The 1973 - 1974 E-bodies employed a different attachment than 1970 - 1972 E-bodies with a 1/4"-20 x 13/16" flanged head screw with 3/8" hex head. The following image shows the 1970 - 1972 screws and 1973 - 1974 type screws compared:

The later screws may vary at the point depending on the supplier.

FYI...
