Ever Modify your linkage?

From that photo angle it appears you are missing a short piece of linkage. The fiinal stick between the lever and the adjusting block. The 904 wont use all of it but it is long enough to acomodate the 727 too. I've had to make that piece.

Any chance of a pic RedFish? The car is not on the road yet and I'm sure there will be a bunch of bugs to work thru. A jump on the bugs is always welcome.
