I still can't figure out how NHRA ever approved the Wiebe suspension system for Stock Eliminator.

I've got the rule book here and it clearly states the lower trailing arms must be non-adjustable and have bushed ends, no heims. Upper is allowed to be adjustable and have heim ends, but not the lowers.

The Wiebe lowers have heims and are adjustable making them illegal the way I read the rules.

Also, the rules state that the upper rear housing attachment point may be relocated, but it doesn't not state you can on the lowers (Alf system drops the lower front bolt below the frame with a bracket), clearly a grey area in the rules.
