I'm Heartbroken. Time to face reality that my Cuda is a parts car.

Three things have to exist simultaneously to get any project completed over any length of time. These are in order of importance: 1. emotional investment of some sort; 2. time; and 3. money.
Emotional investment could be love for an owner, love of the work, distraction from other vices or negativity, a personal history, appreciation of a pedigree, etc. This is first because it will keep you trundling the car carcass around with you, traveling around looking for parts, getting burned on parts, healing from burns/cuts/bruises/exhaustion, and giving resistance to others who say "why do you bother". You have to want it, as they say. And that has to be a strong want.
Time to make progress. Sometimes that steps, even small ones like picking up the garage and sweeping or blowing dust off it. You need to find the time, or make it, to offset collecting years of tax returns, or weathering kids between birth and 23, or family responsibilities, or career development.
Last and IMO least is money. Money to store it. Money for parts. Money for tools. Money for labor you simply can't handle or believe you can't handle. Money to keep life paid for so you don't need to liquidate the car(s).

I have six cars. One runs. The others are close to or are basket cases. Two are flipper/investment cars. Three I have personal history with (good experiences, owned in my teens (I'm almost 49), etc. One is only there to recreate a car I have fond memories of. Nothing will be completed for more years. 4 of the 6 would be considered parts cars if I was looking at them as a buyer. Well, maybe 3 of the 6... Anyway the ones I have, I have reasons for. I take time when I can. Sometimes I have none for months. Sometimes I have a lot but don't have the money for what I need. Sometimes I work on others' cars to finance my own. The last car I painted was barter for years of dry storage...

We don't all have a ton of money to write checks or buy a perfect car. So you do what you can. If you've lost the motivation because the job is too big, get rid of it and either lament the loss, or find one that's better. Just understand that at this point unless you're very lucky, whatever you can afford will be in the same shape as what you have. If you had the money to write a check and fix it you wouldn't be in this position. So I'm assuming you don't have the money for a better example.

I didn't read the last two plus pages but that's where I'm at. I think you should decide if you can commit to fix it, or just cut strings and move on to something else. Maybe you already did that...lol
