Upper trailing arm difference

What's the difference between '64-'67 uppers and '68-'72 uppers, are they different lengths? The lowers are the same IIRC, right?

 

The lowers are the same the early uppers are (if I remember correctly) longer than the 68-72.

 

Thanks for the reply John, can anyone confirm this?...... Thanks

 

He is correct. The 64-67 uppers are longer than 68-72 uppers. The lowers are the same.

 

Thanks Brian, do you happen to know off hand how much longer the early ones are?

 

I have them both on a CAD file........ if you remind me I'll get you the lengths, center to center............

 

Thanks Steve, appreciate it.

 

64-67
Lower "21.875
Upper "12.750

68-72
Lower "21.875
Upper "10.25

 

Wow! I wasn't expecting a 2 1/2" difference, thanks for the info Steve.

 

That does sound like a lot....... that's what my CAD files show and I've built a few sets on those measurements.........
