from the receipts i got when i purchased the car, it listed heidts as the mII supplier. it is mounted on a fatman stub frame. of course, when calling heidts, they advise they dont make any such animal for my particular car. otherwise, ive been very happy with the car as it stops steers and tracks well. was/is very nicely put together, but i need stronger springs. at time of new springs, i also instaled gabriel heavy duty gas shocks. all was right with the world for approx. 3 months.
will check on the grain co-ops or get to a truck stop soon. kind of disappointing to put all that work into it just to get same results. not like it was a ton of work, but like most, i dont enjoy having to redo what i just did.
