Title: Emergency Brake handle hardware
Post by: Anghelrestorations on May 28, 2023, 01:41:16 AM
Wanted to see if anyone else has seen these style bolts used to hold the emergency brake handle/fresh air duct handle to the lower dash on a 65 Mustang.  This is a April built Dearborn car and at first thought it was a mistake but just randomly was watching a video online and see the same exact bolts used on another car.....so wondering if these are actually correct.

Is this April 64 or 65?

Did you get any info (VIN or projected build date) from the car in the video?

Will look through the collection to hopefully help determine if this was a mistake/issue or running change. First six examples I pulled up through the whole production year had the typical style we are use to seeing

What is not apparent is the threads and lengths of those two screws (those pictures are only worth "500" words). The brake handle has a pair of captive nuts which should be 5/16-24 threads (the specified bolt is 50831-S, 5/16-24X3/4 Pan Head) and the service replacements are the same threads. The heads and lock washers in the pictures are similar to seat to track hardware, but that hardware is 5/16-18 threads. (In 1967, the brake handle attaching hardware was changed to 379949-S2, 5/16-18X1.0 Pan.) A quick "look-see" revealed no Mustang hardware with that head style in 5/16-18 threads.

I have the car (not in the video) in my shop here and that has the 5/16-24 thread on these bolts.  So although they look like seat track bolts they are not....assuming all seat tracks are the same which I think they are.

This is an April 65 Dearborn car with a VIN of 5F08A713454

Thanks. So looking at examples from that production period (focusing on approx 600,000 through 790,000 I found that like earlier examples my examples had the typical expected hardware used  for purposes of holding the fresh vent (and in turn the E brake dash support) bracket to the dash
