I just recently did some back yard shinanigans to my 65 stock struts, but Im not sure you have access to a welder, spring compressors etc etc. Long story short I used KYB agx adjust strut inserts with the bottom nub cut off,front and rear part #765015 repositioned the spring perches up the strut leg about 2 inches, and converted the rear to take a strut insert. the agx strut has about an inch longer stoke then the stock strut so the additional inch just adds to the spring preload a bit. There is a much more detailed article in here regarding the AGX strut swap. I am happy with mine. I have ran 2 Rally x events and they have held up great, I even drove the car off an 8 inch sidewalk at 30mph to see if it would bottom out, and she took it like a champ. Not quite bolt on but only cost me 390. and some labor for four way adjustables and a 2 inch lift.
