Pumpkins do not have to be the same to have the same spline.
and they would not bother me if I had a good tig to make one fit.
or a charger / challenger.

Mmmm
we should keep that also in mind since the charger and challenger where mercedes design.
seriously the k member from a challenger looks identical to ours. From pics...
and if it was, than the options get blown wide open.
from gears, axles limited slips suspensions wheels everything on the rear....
