I got something weird going on with mine. I do not know if the previous owner put longer springs on the rear but, I guessing he did.One side is at about 22 degrees and the other is dang near 35.

m151 or m151a1? Curious cause the spare is an early mag rim. I don't see a slot for the gas tank strap for a straight though now that I look closer...

Always possible somebody swapped in the wrong springs for some reason. Sure you are not just used to the design? Everybody that takes a look at mine always asks why the rear tires look canted in so much from bottom to top \----/ and I have to explain about how it was first built and why the design was changed to trailing arms.

If it has shocks they are the wrong ones since they are what limits the suspension travel.
