Those shocks are pretty, but you will have to make some oddball bracket to fit them to the car. This is sorta like buying a hat that is too small, then going to have your head shrunk. Why don't you just buy the correct shocks? if money is an issue, consider the time and materials you will spend trying to make the wrong shocks fit your car.
Andy F has posted a red 68 Valiant using the same wheels that you mention. To fit them, they spent HUGE bucks on brake and hub upgrades. It may be possible to do with stock 4.5 bolt pattern 11" discs for far less money. There was a thread on the topic of these wheels and the spacers needed to mount them. The thread is in THIS cornering forum. There are pros and cons over using wheel spacers, I'm sure that you are aware.
