I hear ya.  I've been fairly steadily working on mine for about a month and a half.  I swear these cars used to be easier to work on.  Now it seems like no one has anything for them in stock anymore, and everything I do I get hit hard by WYAI.  I recognize that there are still things I either never really messed with, or just thought good enough when I originally put the car back together.  

My most recent was that in the process of finishing up my Fox serpentine conversion I realized my existing electric fan wasn't going to work (new radiator is too thick), so I am building a dual fan setup, which required me to redo the fan wiring, so WIWAI I decided to redo my headlight relays, add a relay for the horns, and properly integrate all of that into the headlight harness.  I wanted to use the correct color wires for the work too, so I ordered up all the correct colors, with the correct traces (though they are spiral, not straight as factory).  I replaced all the headlight wring from the relays out with 14 gauge, built new headlight sub harnesses from scratch, and in the process of that realized that the headlights were not held in correctly, none of the adjusters wanted to move, etc.  So I replaced both headlight buckets, all the adjusting hardware, the door hardware, and the trim rings.  Removing and installing the adjusting hardware with the headlight extension in place was a TON of fun, but I got it done.  In the process I realized one of the windows in the right extension was never punched out from the factory, making it impossible to adjust that headlight correctly (the bucket would hit it), so I cut that out (I also needed the access to get my fingers on the ratcheting off angle screwdriver I used to remove the screws for the lower adjuster).  Of course one of the left side adjuster screw holes was stripped and I had to fix that too.  

Then I realized that to use the Mustang Steve '94-'04 Cobra front brake setup I actually needed the drum brake hubs for the front that I think I threw out 30 years ago I ordered up a reproductions set (ACP, very good quality, bought from Kentucky Mustang).  I went with all new bearings and races, knocked the hubs together and painted them.  This just gets the rotors and calipers on the front of the car.  Miles to go before I sleep it seems.  

Ugh, really wanted to have it roadworthy for my reunion this weekend, but that seems unlikely.  Oh, well, another couple weeks it'll be back on the road for sure, so it wasn't completely in vain.  

Stop making excuses not to drive it and start making excuses to drive it :-)

TKO it always snow balls when taking what should have been a simple project. 

You guys are correct, I just need to hope in it and go for a spin.  Right now I'm headed to Home Depot.  Lol
