Getting my 1996 GT vert back in good condition.

I recently bought a 96 GT vert with a 4.6 and 5 speed. It had been off the road for about 5 years. It was worked on by a mechanic that replaced the fuel pump and put in a new battery.
The wheels were corroded and the tires were 12 years old, so they had to go. I found a set of 2018 Mustang wheels and tires.Next I started tackling the issues with this car. I changed all the fluids, belt, tensioner, and hoses.
It wouldn't idle and I had a check engine light on. I changed the idle air valve on the inlet and that corrected both issues.
When I filled the tank for the 1st time, it smelled of gas, and I found the seal for the filler pipe leaking. I've replaced it and now no more gas smell in my garage.
I next went after the front leather seats that were showing cracks and much wear.
I bought restoration supplies from 'The Seat Doctor" to repair them. 1st I used seat crack filler and dye to make the open cracks less noticeable.
I then removed the plastic hood scoop, and cleaned up the hood.
The hood still needs a little more work.
I cleaned and treated the top with vinyl protector.
The carpets have been shampooed, but need to be replaced because the PO was a smoker and there are several burn marks.
Next, I need to find the source of the antifreeze smell after driving and parking in the garage.
I'm hoping to be able to drive this for a long time.

The seat is doing great. It looks well worn, but not open cracks any longer.
I've put new headlights and turn signals one it.
I had to replace the headlight switch, and the idle air valve. I also replaced the gas filler tube seal to the tank.
It's slowly coming together.

Update on the seats. I put my elbow through the back of the drivers seat while searching for my phone that fell to the floor under my feet. I had to get out and then on my knees to reach it. In doing so I leaned with my elbow against the seat back. RIIIIIP went the leather.
Anyway I found a seller on Ebay that had a leather replacement for both front seats. They fit well and look good.
I was able to reuse the foam buns by carefully cutting the old covers that were glued to them.
