Hi Tony

Before you install them could you do us Chevy Nuts a favor and measure them. You may have found a source for us all.

Need length, OD, distance from end to center of the locking cross notch, approximate dept of the locking pin notch.

Cheers Phil

Will do!

I can start with length of 4.28" & OD of 1".

I know those measurements off by heart.

The rest i'll post this evening, when I get home.

Hi Tony

Thanks for that information they won't fit HUPs but now I will have to find my overhaul notes on pins for the C60S and C60L.


If anyone curious I have the HUP pin and bushing dimensions http://canadianmilitarypattern.com/H...ril%20Work.htm

I have hope that it will turn out that the pins you have found through MAC's will also fit the big Chevy CMPs.

Cheers Phil

Hi Phil

the Pins for the C15a are no longer available from suspension shops..... I had mine done...... was quoted $60 each.... had them done for $40 from drill rods in a rural machine shop...... then found that Dirk had them at LWD NOS and cheaper.......

The machine shop cost comes from using drill stock..... heating them to remove the temper.....drill, cut the bolt lock and tap for the grease fitting them re-temper.... hope they will alst longer than the 70 eyars old originals.

Follows are the dimensions of rear shackle bolt, as requested by Phil.

It's hard to hold caliper still while taking photo with other hand, so I have taken the measurement first, then tried to hold in the representative position......or close enough to know what the measurement refers to.........I hope.

Length.

Distance of groove bed start from end of bolt.
Rear pin groove base start from end.jpg
Distance of groove bed end from end of bolt.
Rear pin groove base end from end of pin.jpg
Groove total width.

Depth of the pin groove is 0.1185" below surface of the bolt, give or take a couple of thou.

Total width of the bevelled surface each side of the flat groove is 0.075"

Don't ask what the angle of groove bevel is, it's not 45 degree, but cannot find anything precise enough to measure accurately, and I am not learned in the ways of the force!

Hi Bob

I had to enlarge the pin grove in the pins I got instead of taking the hardening out of the pins, ground the groves larger. Took about and hour to do all the 6 pins. Can post details on cutting the groves if anybody needs it.

Cheers Phil

Hi Tony

Great detail on the measurements as the old saying goes 5 pictures worth 5000s words.

Cheers Phil

HI Phil

If memory serves me right the original had a trench groove cut with angled walls that matched the special bolt with similar flat angular sides. No wonder they are no longer making them.

Surely the end of a new flat rectifier grinding disc would do that in a jiff. Not precise but good enough..... the groove / bolt attachements is only to keep the pin in place from moving sideways.

On my Chevy pins there was a grease groove cut around the pins centered o the grease outlet hole. Maybe the Ford was different.

You also need to find the suitable bronze bushing.
