I've attached a couple pictures that show the finish on my 68. I'm not at home this week to inspect the car in person and give you exact details on the finish but I hope these will help.
You can see that some of the rear deck lid hardware was installed before the car was painted and others after.

That latch/lock you show is kind of interesting. It’s in the 68 and 69 AIM with same #3942775 & 6 but had to, and does, come in two versions. What’s confusing is the genesis of that lock and its acceptance of the stud for soft tops and then having to accept the hard top early 68 stud then later the bolt with washer and nut system. If that spring over laid the hole you couldn’t get the bolt to the pass through for the hard top. The funny thing is the part number remained the same but the spring had to change from blocking the hole to a side mount type. This had to be a critical component for hardware compatibility. Early cars with that lock, like yours, could only accept the stud no way would the bolt pass through yet the same part #. This configuration mismatch could get you in a world of hurt. Do the judges look at correctness of function as well as timing, per AIM production? Also in the 68 AIM (prior to12-27 67) it was even called a lock that used a bolt?????? The reason I ask is I have one each style lock on my car and have a garage top I never use and probably could not? Actually I could by using the studs and not the bolts.

I don't have access to an AIM right now but if I remember correctly either the 68 or 69 AIM does show a part number change for the lock assembly. With the early type lock that I have it would be impossible to use with the later stud, washer, and bolt hold down system.
My car is hard top equipped and it is interesting that the soft top uses the large diameter pins (stud) in the rear bow while my hard top uses the earlier smaller diameter pins. So both diameter pins were being used on the assembly line at the same time.
The last judging guide I have (purple cover) makes no mention of the changes that occurred to the rear latch assembly and hold down method. I do know there is a new judging guide that is soon to be released, or maybe it has come out by now, but I don't have any idea what it says.
I don't judge that much so I don't know how common deductions for incorrect rear hold down hardware are, but I would think they are few. I don't think very many judges would know what differences to look for between early and late cars.

I don't care about judging that much anyway, I just wanted to know about correctness or what was going on during the build. The 68 AIM ASM 1, F1 shows a bolt to stud back to bolt name change in the revisions but keeps the same number for that first bolt to stud name revision. They may have been changing that 1/4X20 stud to the larger 3/8thX16 stud with that last change. This is great stuff trying to unravel the 68. As I said before, with all the confussion, that's why we have two different types of locks with the same number and I have the two different styles on my car. Isn't you car close to mine 13417?

Yes, my car is relatively close to yours, 16,471. It is interesting that you have the two different style locks on your car. Are you confident they are original?
It would be great if we could get other 68 owners to comment on what rear lock style they have on their cars.

Re: 68 rear bow lock/latch
Mine is the same as the one John has pictured and by the tank sheet it is a hard top car, serial # 3907,does anyone know were I can get the small studs that are mentioned in the posts? Also my car has the early style wiper door that is notched out to accomodate the squirters.

Re: 68 rear bow lock/latch
Just for you guys that are just interested in driving the car with a hard top, I use a longer bolt and fender washer inserted from underneath to secure the top. Adjusting those stupid pins and having them hold is tough. Not good for judging but good for function as a driver if you don't want to hear rattles.
My 68 is early small style pins, now bolts. Forgot were I put the threaded pins..........Comment

Paragon sells both the 1/4 (68) and 3/8 (69) studs, 2459 and 2408. But be sure you have the correct bow on the top that it screws into. The lock are probably not an issue usinf either of the studs but make sure you have the correct type lock to use the pass through bolts and square washer.

Don't know if they both were origional to my March car. It would be strange if that offset spring lock showed up in production before the requirement for it in the 4-4-68 AIM revision (stud to bolt).

I finally am home and able to look at my car and AIM. As a thought earlier there was a part number change for the lock assembly. 3915785 & 6 were the early locks with the center spring. 3942775 & 6 were the later lock assemblies with the open center and side mount spring. This is shown in the AIM on UPC 1, page F1 and confirmed by looking at my car. The part number is stamped on the flange of the locks.
I also want to make a correction on what I said earlier in the thread about the size pins used on my soft and hardtop. The hardtop has the smaller diameter pins while the soft top has the large.

Here is the problem, two types of designs with the same number series.

I have good record of a Feb 9 th (11103) car that had the older 3915785 & 6 locks which is way after that AIM Dec 12 67 revision. They probably were using up old stock prior to the stud to bolt change of 4-4-68. That would or could be why my March car was in the transition period to the 3942775&6 and has the odd set. But that still does not answer the why would there be the two different types with same # series. I'm going to leave mine alone, with both, cause it adds to the mystery and should be that way if it came that way.
