Firstly, it's interfering with the rear prop shaft at full droop as the panhard pulls everything over to the right. This I will fix with a longer panhard rod.
Secondly, it's interfering with the upper driver's side radius arm - it won't let that side drop all the way.
Two fixes I can see - a new upper radius arm with a bend in it, or cutting a few inches off the back end of the petrol tank.
I have a couple of questions - firstly, has anyone had the same problem and if so what was the chosen fix. Secondly, if I have the two best options right, which one is going to be cheaper to get done?
I don't think I am going to cut and weld the petrol tank myself for obvious reasons, so I'd have to pay a pro to do this. Same goes for the bent arm really.
Any suggestions? Fitting this suspension is turning into a lot more of a PITA than I expected... but then what isn't?
