Hi,

1) half shafts - 3707775
2) drive shaft - 3742995

Also is the drive shaft identical in size and lenght for auto and 4-speed?

Thanks,

Danny,
I do not believe any part number was painted on a 64 drive shaft, some other years such was done.

Here is a summation I have complied from other comments for drive shafts on the site;

63 initial release 3832043
63 revision (4-63) 3823352
63 4.56 diff ratio 3832677
64 initial release 3843002
64 4.56 diff ratio 3832677 *possible but still ????

65 initial release (6-64) - 3868727 (carried into 66-67)


Remember the 63/64 shafts were mostly covered with blackout.

thoes are the numbers cast into the yoke ends, they are known originals

Re: 64 drive and half shafts?

The numbers I posted are for the complete assembly. Don't have the yoke numbers which correspond to a drive shaft and was unable to read those on either of the originals I have. (stuff in the way).

My reference (Chassis Restoration Guide, Tripoli) shows both drive shafts at 29 7/8" Same source notes no part number for 63-67 just paint rings.

I believe the numbers you are reporting here are the FORGING NUMBERS for the yokes. They are not the part numbers for the driveshaft assembly. However, I think the half shaft yoke forging number is actually 3797775.

Thanks guys, glad to hear that those shafts are original, I am going to paint them now..

Re: 64 drive and half shafts?

Warning! Before you paint the half shafts check around with others who have gone through the judging process. The JG would like to see natural half shafts and all the major rear end running gear. So if you blacken those expect to lose some points. (normally nobody can see drive shaft)

At last regional I got hit lots of points on just that argument even with Sept 1964 picture of an original black 64 under carriage. So if you are on the edge of points for Top this is one area you do not want to miss.
Consider this, if you leave natural as JG wants and in the future when the black is accepted its simple to paint blackout.

Alan -- I'm amazed the '64 judges are still docking for black (sloppily applied). Was the picture you offered as proof/documentation that Motor Trend test article photo ?

Below (on the left) is a pic of a '64 half shaft I have off a late January car, and only used for 4_1/2 years (removed and stored since 1968). The clear areas are those that were covered in black (paint ?) and came off with thinner. The lightly rusted areas are those that weren't exposed to paint, so think of the streaks as a negative image. You can even make out the blue-ish heat affected weld zones. (Ignore the shot-peened '65 BB half shaft alongside). Second pic is of the strut rods off the same '64. All this is confirmed by that Motor trend pic, IMHO. I also have shots of the trailing arms off this same '64 Jan. car, showing the spotty black coating.

Re: 64 drive and half shafts?

Yes, its the Sept 64 Motor Trend, wonder where I got that
What's nice about that photo is that in Sept 64 the 65 was already
on the road so that car should have been one of the last 64's.

Well things are getting better each year and with the rest of the car being so original I can afford to lose points until the JG gets updated. Even have production U Joints for half & drive shafts now.
