69 camaro/firebird rear back spacing?

[jlwdvm]

Trying to get a set of Vinatage Wheel Works V40's ordered for my 69 firebird TA track car clone. Looks like 18x9.5 with 6" back spacing is going to be a safe bet for the front with 275 Toyo R888s and Ride Tech Tru Turn (may have to use a spacer to get it dialed in exactly) and I will be using 18x11 for my 315 Toyo R888s for the rear. The car is mini tubbed and I am wondering what back spacing I should get for the rear. I will be using a Ride Tech 4-link for the rear mounted from the leaf spring perches on the rear so I can't narrow the rear too much. I will probably be ordering a Currie 9". I don't want too much dish on the rears either. Any ideas for the rear back spacing? I'm gonna order the rear end after I get final measurements with the wheel-tire combo under the car.

6" on an 11 will be nice. Not too much lip.

Remember when you mock up to measure your rear housing add the rotor thickness X2
