I have NEVER seen any 67-68 reproduction set which includes ALL of the pieces (missing the 2 push(speed) nuts for retaining the rad support bushing assemblies and the 4 spring washers for the 4 body positions) much less all of the pieces being correct.
The correct body bolt set up for 67 68 utilizes the spring washer as indicated in the assembly manual (68 Manual P. 51, UPC 1, Sheet D1, item#15 PN 3914049 Washer-Spl Spring) and shown in the following photos (silver) PLUS the push or speed nut same sheet item #7.
I have seen hundreds and hundreds of cars which have never had their subframes removed and have never seen a 67-68 which did not have spring washers in positions 2 & 3.
As an aside: I did not take notice of this initially, however through out my 48 month non scientific study and recollection (worth what it will purchase) recalls LOS cars having indented head bolts in positions 2 & 3 where as the NOR cars had RBW's like pictured.
IMHO this has not been covered in enough detail and there are FAR TOO MANY CARS which are NO WHERE CLOSE to being correct.
