Thanks for your answer. I got same kind of answer on other forums. I will do it in this way and see if it works. If not maybe problem with shocks.

Hi all Last Sunday I had to face a strange behavior on my mach 1. The car leaves the garage normally, we got in, 4 persons, about 140 pounds every one, not too much I think. After 300ft, I heard a noice like a metal friction! The left rear end of the car was lowered by 1.6in and stays in this positions. I decided to drive the car back to the garage and discovered that the car has retrieved its normal level. Leafs seems to be OK and shocks as well. The only thing I could see is that the collar fixing the left leaf around the rear axel has moved (see picture) On the picture we can see original collar position! Any idea if this collar can move and if this can be the cause of the collapse and level blocking?

Hi, Thanks for your help. It's a FMX, 3 piece :thumbup: I can now order the overhaul kit.

Hi, I have a mach 1 69, but I don't know which kind of gearbox is installed. In fact initially this car was sold with a manual gearbox but one of the previous owner changed for an automatic gearbox. On the documents I have got with the car I can see information about FMX, C4 and C6!!! How can I be sure which kind of gearbox is installed? Thanks for your help. Spider69

Hi Black Jade, Very nice car, looks brand new. A shame that I'm to far to attend the Nats, I'm from France. I have to plan to visit such kind of meeting during my next trip to the States :-) Hopefully next year or earlier if possible!
