Looking great Nick!
I tried to zoom in on your R's rear shock sticker (the yellow one)
I'm trying to read the part number.
FR3Z ?????
When you think about it could you please post the front and rear strut/shock numbers please.
Thank you.

@8250RPM Front Strut is: FR3Z18124T, Rear: FR3Z18125S

Are you considering an upgrade?

Have you found any unexpected damage?

So far a few things: Rear brake pipe (in addition to the hose that I knew was bad), Fuel tank deflector shield, Engine Mount and Fuel Pump mount. Fortunately all of which are not too spendy. The good news is I've managed to salvage a few parts that I thought I might need to replace. Hopefully there aren't too many more surprises

The expected damage was bad enough. Can't wait to see the new 58.

I may consider it but I'm also going to wait and see how the ridetech controller goes. I've talked to Cortex racing and they said it's better than the R.

The BIW is still at the paint-shop, but pretty much finished tearing down Wally, with no more surprises to this point.

Meanwhile, got the solid bushings installed in the Rear subframe:



Solid Diff mounts too:

Just had a few more parts delivered:



Now I just need the Body back from paint to start the build.

Have you verified that the motor was ok?

Turned it over by hand -- still has compression and nothing appears to be broken, but will teardown for inspection.

Exterior trim kit? License plate-BLACKGT4

The OEM FPC exhaust headers look interesting. Are those cast iron or a cast alloy collectors with stainless steel tubes welded in? If so, that is nice welding. The number 5 cylinder primary tube has an interesting profile.

The new sub-frame bushing look great, should be a great improvement on track.

You have made a lot of progress. I hope you receive the newly painted BIW soon so you can begin the joyful stage of this build.

In regard to the engine, you mentioned an inspection tear down. Which made me wonder if the engine did not shut down during the early stages of trouble? I thought perhaps the fuel system would have shut down.

Just hate to see you go through all that trouble.

On the lighter side of things; after going through your build thread again and seeing the of the scope of this epic build, it occurred to me that those boys over at GYC have it comparatively easy! Very nice work.

No -- still waiting on the BIW Exterior kit, which is why the car is still in paint (it includes the Rockers and Rear facia).

No license plate for this car, but I like your thinking, Steve

The headers collectors are cast stainless and are HEAVY! I'm not 100% on the grade, but I'd say 409 stainless. At least on the tubes.

Yea, the welding on the Headers is very neat. They will get swapped out -- just have to choose between Kooks and ARH.

Fuel pump cutout shut down the motor, so I'm hoping it's good.....

Got the wiring harness and suspension height sensors re-assembled on the rear sub-frame today, and also repaired a couple of pigtails on the Engine Bay wiring harness:

 

[steveespo]

Nick please buy American Racing Headers.

 

[Tob]

Really enjoy watching this come together!

 

[8250RPM]

Yes I agree. American racing is the way to go.
Of course I'm biased. I prototyped them for American racing on the GT350 [emoji3]

Paint was delayed as the Body Exterior kit was on back order and includes the Rocker panels, rear facia and mirror covers that all need painting. Planning to pick up the painted BIW and exterior kit tomorrow pm

 

[Black Boss]

Any guesses on paint color?

One hint: Interior is different to the exterior
