*NEW Jan. 7, 1999:  Thanks to 'Drew Peroni' from the EBR, he sent me a frame specification diagram, with measuring points and specs, etc.  I have it rotated sideways so it will fit on your screen/print good.  I made them into .gif89a as well as .jpg, left one each as full size, and one each to fit on a 800x600 resolution (smaller.)  They are all the same quality, the .gif just does a better job at black and white diagrams as far as file size goes.

*NEW Oct. 8, 1998:  Thanks to 'Van Weaver' from the EBR, he sent me a 1977 Vacuum diagram  Not
the best quality, but very large.  I rotated them sideways for easier printing (at least for the small
version.)  Here are small and large versions:
77vac01 (85 K)
77vac03 (420 K) same as 77vac01, but a lot bigger
 
 
*NEW Feb. 2, 1999:  Thanks to 'Phil Lindenmuth' from the EBR, he sent me some great EB rear axle info:

Code  Weight Rating     Ratio    Type (Locking really = Limited Slip, not a real locker)
A3     2780/2900*        4.11     Locking
A4     2780                   4.57     Locking
A5     3300                   4.11     Locking
A6     3300                   4.57     Locking
B8     2780/2900*        3.50     Locking
B9     3300                   3.50     Locking
03     2780/2900*         4.11     Non-Locking
04     2780                    4.57     Non-Locking
05     3300                    4.11     Non-Locking
06     3300                    4.57     Non-Locking
08     3300                    3.50     Non-Locking
18     2780/2900*         3.50     Non-Locking
19     3300                    3.50     Non-Locking

*  2900 lb axle replaced 2780 lb axle for 1976-1977
    3300 lb axle = large bearing
    2780 lb axle = small bearing
    Not sure about 2900 lb axle
 

Wiring Diagrams

You will probably need to view/save/print the identification keys for circuit symbols and for electrical symbols.

I also have bulb and fuse specifications.

(4-24-97): I have founds some more diagrams from 66-72, in better shape than the previous ones. The "66-71" scans are generalized for those years. I now have that same period split up into separate diagrams. The 66-71 diagrams are all very similar with just a few modifications due to more accessories in newer years. Usually there is only a slight color change to a wire or two. These are all now in gif89a format, so I made them a lot bigger and they take up less space than before when they were jpg's.

*NEW Oct. 8, 1998:
I got these diagrams from Eric Neasham (EBR/NVB mailing lists.)  They are very good quality.  I had to shrink them to fit the resolution better, and I have them sideways so they will print out easier.  If you save them on your computer, you can always have your viewer program rotate them to proper orientation for viewing.  These are from a 69 EB.

The 73,74 diagrams were tough to read to begin with. Some pages of the wiring diagrams were not available, espec. on 66-71, and 73,74.

Please take the time to save these on your computer after you access them.
