I need to raise the rear of my 240

[Guest 305240]

After thinking I had it all figured out, I ran into a problem. I liked the stance of my 72 240 with the 302 settinig in it. Nice wide 10' tires in the rear with the flairs setting about 2" above the tires. The flairs are made so they cover the gap to the original fenderwell.

 

Now the problem. I discovered someone had put a set of twist rizers in each spring. All I can see now is the flairs setting and rubbing on my tires. My question is: I have a 76 with a R200 in it. Can I change the complete rear suspension to gain more rear height? I also have a 78, but that's a R180. Thanks in advance for all input and views.

or, you can just take strut mounts from the 280z rear and put them on the 240 to gain 3/4" rise.
