I've also had good luck at Fastenal finding bolts in various sizes.

You can get those bolts from McMaster Carr on the internet in either partia=
lly threaded or fully threaded.  You will probably have to buy a couple to =
get them.  Very fast service!

The Collective,

I'm working on the Spitfire's traverse leaf swing spring rear suspension an=
d can't find locally the 7/16"  fine thread (20 tpi) by 3 1/2" bolts that w=
ere holding the vertical link and to the trunnions and to the swing spring =
bushings.

I can find the right sizes in a coarse thread (12 tpi) grade 8 bolt and tha=
ts my plan. The old ones are grade 5 or in one case a bolt with no slash ma=
rks on top. I don't know what it is.

Do these bolts need to be fine thread for any particular reason, e.g. for s=
afety, torque specs, etc.? Is a grade 8 bolt a good idea where it will be s=
tressed with all the up and down motion with the vertical link? Too brittle=
? Usually I go for grade 8 whenever possible but I've heard there are insta=
nces where it might not be the best solution.

An aside for Thanksgiving:
My son and his wife teaching in Shanghai said the Chinese love to celebrate=
 American holidays (they know them from American TV and movies) but their t=
ake on Thanksgiving is that you thank people who do nice things for you. So=
 they got cards from their students thanking them for teaching. Kind of a d=
ifferent twist but a good one I thought.

Happy Thanksgiving to all.

Thanks,
Bud Rolofson
