Frontwards , backwards, right, wrong -- supposedly these correct 60-68 tow hooks in my opinion are overkill for a 1/2 ton or 3/4. I bought the pair and they had what I think are the original 5/8" grade 8 fine thread bolts and I mounted them with 4 new grade 8 coarse threads with the thick washers and lock washers on the inside. I used 69 front leaf spring hangers --I do not know if they differ in design of a 67 K10 but there was little room for mounting them on the frame.

As I said earlier they both curl the same direction which is not noticeable but either correct or incorrect. If anyone has a pair of p/n 363349-50 that curls opposite mine I will trade you one.

There is no gm info I can find and it appears that 67-72 has more info -right or wrong- on them than anywhere on the web. My assembly book does not show them at all.
