Source for these front suspension bolts

[440beep]

The following bolts came off my 69 Bee and not even sure if they’re correc.

The thick one (4 total) is for the lower arm and ball joint and is a 5/8-18 thread.

The skinnier one (4 total) is for the front caliper brackets and is a 1/2-20 thread. On one of them, the washer broke in half so keen to get replacements.

Are Mopar repros available somewhere, as I’ve yet to find them. May just settle on Fastenal ones.

Post a parts wanted ad and there are lots of people parting cars where those bolts are usable, the ball joints not so much..

Fastenal replacements will work.
Just make sure you get the same
grade. These are grade 8 I believe.
Also, when installing used bolts in
this application, torque to 5-7 ft lbs
over new application specs to
account for bolt stretch and/or
imperfect threads. Coat the threads
with oil or anti-seize before installing.

After more thought and considering the safety around the bolts (brake and suspension components), I think I'm purchasing new bolts instead of trusting used bolts, especially after the washer snapped in half on the original bolt. The 5/8-18 bolt is a Grade 5 (three marks on bolt head), and can't tell what the 1/2-20 bolt is, but will get a Grade 8.
