Raymond’s is the only one to break a drive shaft. It was replaced and has been fine since. The bottom ball joint is tight to get in. Recommendation is a large adjustable spanner on the end of the wishbone to pull it down enough. If you’re still struggling loosen the subframe mounting bolts to drop it down a bit to make life a little easier.
Best to ask MuddyMods themselves as they’re always very helpful.

Front, you need to remove and refit the complete leg, so shock with knuckle attached. Seperate at the ball joint, obviously you’re changing your shocks but the knuckle needs to be fitted off the car. Fit the spacer block off the car. Bolt complete leg assembly into the wing then pull down the wishbone to get the ball joint in the knuckle, I use a large adjustable spanner on the wishbone to pull it down.

If you don’t do it that way it will not go in.

Rear normally there is no need to remove the strut, (I do remove the arch liner first) but because you’re replacing it, undo the strut clamp remove the strut as normal loosening the bottom arm bolts usually makes it easier. Replace the strut etc. personally to make life easier I’d bolt the strut spacer on after the strut has been fitted.
