Hi Don , you sent some info on your build a while back.As I am using the same 325 4L on my car , with few variations in the rear suspension, I am using a pair of QA1 coilovers rated at 200 # . With that I am using a mod on the Toro mount with some add on pieces to anchor the coils and on the lower arms I add mounting brackets to attach the bottom of the coils. With all the knowledge about theses trans axles they need fixed supports to prevent side loads on the diff. So that said I built off the Toro lower 2" tubing and made additional 2" tubing extensions for the upper locations to attach a 4 link suspension . This all seems kind of structural and it is, calculations for Camber are made easier with this 4 link system, many others have done the 4 link system on this forum. My project is not on the road yet, but as yours, a work in progress. The current focus is on running my cooling lines to the front radiator. I would be happy to share my ideas with you. Let me know.
Doug Andress.
