I hopped under there and did my best. Here's what I came up with:
42.5" Center to Center for leaf spring perches, NOT 43" (Clearly not 43")
28" Center to Center for leaf spring rear shock perches
34.5" Center to Center for bump stops (welded to rear housing)
Now just have to figure out how to get accurate outside of drum to outside of drum measurement.
Hope this helps someone...if anyone has the outside drum to outside drum measurements for me to compare to that would be huge.
Thanks!
