This is just and estimate and doesn’t include labor...
I think this Notchback would be a good starting point, it’s the nicest looking Notchback I could find. It’s a Cummins swapped automatic and I want neither of those.
We could use this ‘86 Fox as a parts car, if the seller is to be believed the engine was just rebuilt. We could
delicately remove rip out the engine. and swap it into the ‘89.
If what I found on the forums a T-5 should bolt up to it fine. You can purchase a Heavy Duty one for $1,750.00.
Before we forget we need a clutch, CJ Pony Parts has a clutch kit for $161.99.
We’re gonna need a Driveshaft, once again we’ll turn to CJ Pony Parts and get one for $329.95.
As for Differentials I’ll go with a Quaife ATB Helical LSD for $1,107.23. I’m not sure if this will fit with the T5 so if it doesn’t one of you should say something.
I’d fit a Mustang Cobra steering rack, that’s $289.99.
Frankly, I don’t see the point of all this and not touching the suspension. I couldn’t find a Cobra IRS kit new, so I checked Ebay and found one for $1,299.99.
Um, I guess it would be possible to use the exhaust off the parts car, I don’t even know what to do with the front suspension. I’d keep it tuned for the street. I’m not too familiar with Mustangs...
