Default Half Shaft French Locks Question

Does anyone have a picture of properly installed french locks? I recently replaced the half shafts on my 73 and am having clearance issues with the french locks. Any help would be greatly appreciated.

Very nice job on the restoration and its documentation. The only things I will add are: 1) the available [aftermarket] French locks are not hardened properly, so they are difficult to use and I'm not sure they are all that good at 'guaranteeing' the bolts don't come loose; and 2) the tabs on the French locks are supposed to be pried up and against the flat sides on those bolts' hex heads. They need to be driven flat against those hex-head flats....not against the edge between two flats.

With properly hardened French locks, only one tab [for each bolt head] needs to be pried up to prevent the bolt from backing out. But, with these un-hardened POS parts, you need to use them ALL to be reasonably safe.

Found no locks when I pulled my half-shafts and trailing arms.
Did find frame rot though...
Dammit!!

As mentioned above, get the SS french locks and not the krap usually available. The cheap ones get all bent up when you tighten the bolts.

When Juliet was doing that restoration 10 years ago she was a VERY active member of the Forum. I was often swept up in her enthusiasm! She went on to become an NCRS judge. But I have not seen any posts from her for many years. I do not know what happened to her.
