I suppose there is no way to remove a bush without destroying it, to flip the pin around
I had the bushes and fulcrum pins fitted to the A arms a while back at a workshop. It was a while before the new heavy duty replacement fulcrum pins arrived and I got them all painted up. Trying to measure them fitted is a bit harder to see, but I think one is correct and the other not . I am only measuring about a 1.5mm difference from the larger end to the smaller. On the old pins the difference is a bit over 5mm from end to end.NB Do remember to put the lower fulcrum pins in the correct way round! Identify the "larger" ends, mark them and make sure that they are fitted to the rear.

Here is the long and the short of it, or the the not so long and short of it.
The bottom pin is the new and the top the original. There is a long and a short end to the new pin but not as great as the original. I don't know if this will matter as long as both pins are replaced and both fitted the correct way.
I managed to get one bush out ok but it had the slightly larger washer which would not fit through the bush eye. I had to take the other bush out which did not want to come out without destroying it.

Don't know if this is helpful, but there is a relevant dimension shown in the workshop manual.
As already noted in earlier posts the slots are not the same distance from the shoulders/ends of the thicker diameter. Have a look at Figure 16, Section F, page 22 in the manual. It gives a dimension of 1 1/8 inch (2.86 cm) as the distance from that edge of the pin to the center of the slot on the end of the pin that goes to the back side of the A Arm. Might want to be sure that dimension on the replacement pin is correct as well.

Martin, 165mm C/L which is the same as the original. 175 from the outside edge of the grooves.Is the dimension across the centres of the bolt locating slots 175mm?
Gene, this is where there is a difference. Long end on the replacements are 26.8mm, short 25.3 against the 28.6 and 23.2 on the original.
Yes, you're right Mal, 165mm at the centres. It's been a tough day.
Doing the sums on your measurements means that the new one is wrong.
I personally would reject it but I'm a fussy pedantic sod when it comes to things like this.
Edited because some of what I wrote was incorrect.
