Welcome to
I don't really have anything to add that hasn't been said already. Most of the major suspension companies, and a few of the smaller ones, make a myriad of parts that will fit your car. I would suggest checking out Jason Rushforth's build thread on HIS 64 Skylark. There are lots of great pictures and he is pretty detailed.

Also, you might check out this thread about the same car once it was done.
