Olds ticket to 9s... LS swap adventure.

A single injector lower was back ordered until April. It got canceled.
Small update, I have been busy with work and life but I have been knocking things off the list.
First the 9" tru-trac third member is getting the 4.33 gears the car came with replaced with a set of 3.50 gears at the local trans shop. Sticking with the Tru-trac as its a 31 spline and when I have to upgrade to 35 spline I will spool it then. Thats my plan anyway, I will need a stronger third member the and it'll be easy to get everything from one place.
Second, I think I have figured out the wheel situation I created when I swapped rears to my Quick performance housing.
I have a wheel simulator to get a good idea of what will fit and I have been trying different things to what kind of backspace and tire widths I can get away with.
Rears will just fit 15" rims, just. I had 15" rims with spacers on this rear before so I know It is possible.
The Problem with LS F-Body brakes is the caliper is actually farther out than the wheel mount surface.
I had even ground down the caliper to try and get the Vision 521 rims to fit, here is a comparison to unground to ground down for clearance. These calipers are way past the wheel mount surface before I ground them down. I didn't get very agressive yet.
The fronts are not nearly as bad for fitment. Calipers are behind the wheel mount and shaped better. Pretty good for 6 pistons.
17x8" rims are an easy fit on the front.
After some communication with Weld, 4 of these are on the way. 17x8 up front and 15x8" for the rear.

It will need a notch for 10" with the BS they offer.
When that happens it'll probably be the matching beadlocks.
First 2 of the 4 showed up late yesterday. Had a chance to mock up today. I am SUPER impressed with these rims. Might have to run my 0.200" shims up front to clear the wildwood spindle caps but I can deal with it.
