They have a special shape.

I don't believe you can get new ones but www.vintagepowerwagons.com has recycled ones.

Expect to pay dollars for something that should cost cents.

Cudan,

 

Flywheel bolt 871685 1936 to 1954 Plymouth, Dodge, and Truck

 

Special Hardened Steel 7/16-20 x 1-9/32" long

 

(Your up early Loren)

 

Best, James

 

{PS. It is nice to have an old MOPAR parts database online. Years ago someone had it online and they did not restrict their database for the use of wildcards. I was able to download the whole thing and stick it in a MS Access Database. Now I can look up parts in my books and x-ref them with the Access Database!}

Thanks,

with this info I can search them overhere.

I wonder how well ARP 743-1250 would work?  .030" shorter than 1 9/32 (1.28125")

If one can get ARP in a size that would work...then I would most certainly do that. Of course I wonder way I bother to list the size ?

Summit racing has them in stock, Amazon shows some in stock, Ebay shows some selling.

 

Summit is cheapest by far.  Still need nuts and whatnot though.

I plan to have the machine shop tap my crank and go with ARP 1/2" bolts
