So, after reading the above posts, it seems like it is possible to, in my case, possibly convert to using SU's maybe?. Obviously as stated in above posts, a heap of good advice and procedures to consider in doing this properly though. It sounds like they are of high maintainance to correct and run properly (maybe that's part of the fun?)

I'm interested in doing this as a project though.

Are there any clips out there on A12's with SU's I should have a look at, I really like all of the different things you can do with Datsuns but I reckon, just in my case/preference, I'd like an SU setup over some of the more I guess, cooler, more powerfull things out there.
