Repa rear seat belt bolt size

[Bjaramillot1502]

Hello everyone.

 

Recently I bought a complete set for rear Repa lap belts but they didn´t came with the bolts.

 

I don´t know if the size or thread are different on the latch side or the buckle side, so i marked them with different colors on the picture that i found on the forum.

I just want to know what bolt should i buy to same me the trouble of testing different ones till i find the correct one.

 

Thank you for any help.

7/16“ is standard seat belt bolt size. The bolts that secure the belts in the middle are 25mm long shoulder bolt (see pic).  Not sure the length on the ones holding the retractors, but they are about the same length, standard bolt, not shoulder bolts.

Yup as Karl said 7/16 the thread is unf 20 per inch. If you need to you can use a small spacer cut from steel tubing to replicate the shoulder bolt.

Thanks to both of you.

 

Just one more question, how long does it have to be the spacer to make an stardard bolt into a shoulder one without looking for a shoulder one because I don't know if I would be able to find one.

It shoulder needs to be deep enough to allow the seatbelt mounting and the 2 washers that let the belt swivel up and down so something like 3/8th of a inch.

Thanks, one last question, how thick do the washers have to be.

 

And I imagine one should be made of from nilon so it could swivel

I don't have a measurement on the washers but they are not real thick and yes nylon or the like so they allow some slip.

Nothing special about the washers.  The "standard thickness" flat washer for a 7/16" bolt will work just fine.

Some of those washers are cardboard or something similar.
