Just Purchased GT Convertible, Should I Use for upgrades or try and unseize the engine? Options

[gbloomer]

This is my first post on here. I just came across a 99 GT Convertible for a few hundred dollars and jumped at the chance. At the least it would provide several upgrades for my ST. The interior and the exterior are in pretty good condition(the pictures dont do it justice) the odometer is at 122440. But the engine is seized up, long story short their son took it walmart and they only finger tightened the oil drain plug. It vibrated out and he ran it with out oil till it seized up. Do you think it would be worth it to try and unseize it? Or should I just use it to upgrade my 95 ST and part out what i dont use?

pour oil in it and unseize it.

WD-40 and pour some in each spark plug hole. The first time leave it sit for about a week but keep adding the WD-40 every other day. After the week is over take a breaker bar and put it on the crank shaft bolt ( make sure that you turn the way you would tighten the bolt ). Never force it to much. If you can get a large hammer in to tap on the breaker bar. Once you get a little movement work it back and forth. It will eventually turn.
