super swinger is underway!

I have a few pics of how the cobra rims fit the front of my car.The engine is out,so the front is up high,but i have plenty of clearance of everything,even with the wheels turned in both directions.I do thin the 245/45/17 are a little large for the front,so im planning on buying some 205/40/17s.i still havent gotten the rearend swapped in yet,but im thinking at this point i will try to run 275/40/17s on the rear.Im not sure if the 8 inch rear end i have will work or not.I found out it is out of a 64-1/2 to 66 v8 mustang,the weaskest ones avalible of course.The ford guys dont even want them,its just my luck to get stuck with one of them.I guess i will wait until i get the 73 duster drag car project home,so i can rob the 8.25 out of it.It is a 340 car,that someone gutted to finish another project.anybody have a 8.25 posi unit for sale?
