65-66-door hinge questions

randy66gt350 · Feb 1, 2004

I installed my reproduction door yesterday on my 66. When I went to install it, the threads for the body side of the hinge were 5/16, while the threads on the door were 3/8. I have new reproduction hinges from Year One and a new bolt kit from them also. The bolts (all 22 of them) were all 5/16. The hinge shouldn't matter as it is just clearanced for the bolt. The threads are in the door and in a plate on the body side. Year One lists a different part # for 65 and 66. I'm wondering if maybe the difference is the diameter. Their tech-line wasn't open yesterday and I need to know how to get the correct bolts. I pitched the originals when I took the door off a year ago and threw out the door (it was rusted too badly to save). Has anybody run across this??? I've currently got a hodge podge of bolts temporarily holding on the door.

Hmmmm. I can only suggest contacting your source. IMO, '65 and '66 hinges amd bolts are the same.

BTW, take from this a lesson of the old car hobby: "Never throw anything away." (certainly not until you have the replacement installed and functional)

I had the same issue on my 64 1/2 when I went to bolt up some replacement rust free doors from a 65. When my original bolts would not fit the replacement doors, I just assumed it was another unique feature to the 64 1/2. I just went to my local Home Depot and picked up 3/8" bolts and bolted up the doors. I can't offer an explanation here, but it is interesting...

Thanks.

Dave,

I normally agree with holding old parts until new are in hand, but with fasteners, I tend to get antsy and use old nasty ones that should be replaced...If I don't have 'em, I can't use 'em.

I spoke with Year One this morning. 1965 Mustang doors had 3/8 attachments. I have a 1965 kit on the way.

Randy: Good to know. Thanks for thee feed-back!

BTW, I have coffee cans full of old fasteners that I use all the time. Often they can be cleaned up and used when a suitable replacement isn't readily available. For example, I recently "restored" some SEMA bolts used for attaching early fenders. Of course, I'm a detail freak but that's by choice NOT necessity.
