1. Go fetch a pair of mounting brackets- ones off a dead Clubby will do. You also need 8 bolts 1/4" UNF x 3/4" & spring washers, and the Clubby's 2 lower shock bolts (3/8" UNF) & nuts.
2. With a 1/4" UNF tap, clean out the 8 threads in the body where the brackets go. Paint brackets & bolt on. Note the shock mount pins go to TOP..
3. Remove the top bumpstops from the top arms
4. Drill out the top arm bolt holes to 10.0mm to suit the 3/8" bolts. If they are too hard to drill, give up... Shocked and go buy a pair of M8 x 100mm Unbrako cap head bolts (grade 9 or 12) and 4x grade 8, 8mm nuts instead.
5. Drill the top bumpstop brackets to suit whichever bolts you are using.
6. If using the 8mm bolts, I make 2 steel bushes 8mm ID x 3/8" OD x 25mm long to locate the bolts in the shocks- but they probably not absolutely essential.
7. Shocks- you only want stock ones, not adjustables or hard ones. I've run Pedders for 9 years and they are still fine.
8. Use flat washers between shock and bumpstop bracket on top arm, to ensure shock is `vertical'.
9. If using the 8mm bolts, the extra 2 nuts are locknuts, just to ensure they stay tight.
