Re: [AMC-list] Identify 65 AMC 20

Thanks, kind of a nice pressure cooker out in the sun today. 
   Alas, no tag at all, no evidence of one ever existing in the trunk either. The drive shaft followed the trans and came out of the tube completely, while some crud and rust. It still seems tight and functional.   Is there any pitfalls in rebuilding that CV?
   Have to pull the cover a do the gear set check tomorrow. 

   If it is a twin grip, I will likely rebuild it completely and roll it under that car done.

3:15 was a fairly common gear, all automatic 327 cars got it. It was standard for 232, 287, and 327 autos actually. Oddly the 287 with "Shift Command" (three speed auto with now common P-R-N-D-2-1 shift instead of normal Rambler P-R-N-D2-D1-L) got a 2.87 axle in 65, all others 3:15. The only other gearset used with the 327 was 3.54 with all stick trannys (three speed, 3+OD, and Twin-Stick). 3.54 isn't even listed as optional for the autos. So you can be fairly certain it's a 3:15, just have to look at the diff and see if it's a Twin-Grip, so the cover has to come off. None of the ratios share the same number of teeth on the ring gear, so just count those (11/39 for 3.54, 13/41 for 3.15, 15/43 is 2.87). If you come up with something different I'll check 63/4/6 TSMs.

The tube and shaft come off as a unit. The braces bolt onto the tube, are riveted to the axle. Just take the nuts off the studs around the pinion area of the axle and pull the tube off with the shaft in it. The braces then pivot parallel to the axle. The shaft might take a good bit of a tug to get off, it's been on there quite a while!

There's all the details I was looking for!
    I was hoping to get a clean easy identity on it, oh well, probably have to open it and get a firm identity on it.
     Would love to find 3:15 twin grip in this one. It was a drum front brake car. So redoing its brakes should be fairly off the shelf and easy.
    Plus it can be cleaned up and gone through with pulling the convs existing axle.

    I am correct that the Tube, drive shaft and diagonals can be pulled off fairly easily to reduce it foot print for storage? Correct? Any tricks in doing this?
