No the balljoints stay in place-you just have to pop the tie rod ends off the steering arms on the wheel hubs using a tie rod end remover tool or a "pickle fork". The radiator stays in place too.
I cut off the stock rubber boot clips and used hose clamps to hold the rubber boots in place.
Thanks for posting photos of your Tiger! My favorite color too-is that the original paint? If so try and keep the car as a survivor-there are too few of them left….
