I picked up these springs recently.
Off of a Bj40 1980's.
Which is the front and the rear

Have a partial part number 80171-A Might be 60171-A
This pack has 5 leafs
Measuring along the top of the leaf from military wrap end to center pin is 21 1/2" Center pin to non military end is 22 1/4"

The other spring I have no part number
The pack has 6 leafs
Measures from Military wrap end to center pin 20"
Center pin to non military wrap end 24 1/2"

Curious which is front and which is rear

Thanks

I don't have those springs, but just in general, your rear springs will have more "arch". You can read here:

Good luck!

generally the front carries more weight thus more leaves.
For example the stock pack is 7 leaves up front and 6 in back
