Hi SesameCrunch,

10 inch will be ample, I used a screwdriver with 8.5 inches of clear length. Don't be surprised to find a slot or philips head bolt. There is a very good scale drawing of the front suspension (F Frame) in the 'Moultoneer' No 37 Winter 1993. It was available on the old Moultoneer web site but I have not been able to find the current link. Being cross sectional and to scale it is more useful than the other diagram available on the site. If the worse case occurs the bolt may need to be drilled out, a scale drawing may come in handy!!
Also the advice on being careful with the cir clip is well taken, it can take off with out being seen again.
If you are having the forks sandblasted and powdercoated, be sure to protect the serrated section and only have the forks themselves coated/painted.
The rubber boot can be replaced using a boot from a car steering/universal joint, I found one at the local garage and cut it to size.
