I'm 35 miles from Track, I've been in that shop way too much over the years!
When you buy something they start logging your total spending with simple zip code and last name.
I asked them once, "Hey,, what's my total?"
He told me.

That Vincent is a far cry from a box kit. You'll spend 15hrs installing that butt plate alone. There ain't no holes drilled for nuthin,, you gotta make each drilled hole yourself. Through the metal parts and wood. (each one)
That lock won't just drop in that hole,, an there ain't no taped/threaded hole in the lock for the screws,, you gotta drill them and tap'm.
An that shop ain't nothin like a store where ya get to shop around and look at different kits all ready an such,, it's a counter,, you ask for a part you need ,, he goes back an get's that part.
You walk in that shop and ask for a Vincent kit,
you will get one person to help you and they are good people, but your gonna stand there for an hour while they gather all the stuff. They'll let ya pick the wood.
Now I ain't doggin TOW, an I ain't doggin the Vincent. Don't get me wrong.
But you step up to a big boy kit
from any of the suppliers, there's a lot more going on.
Instead of just drilling another hole for the tang screw,, you gotta fit the tang (after you've fit the breech plug to the barrel then the tang to the hook and inlet those in the proper position) choose where to start the hole through the metal of the tang, then determine the angle of the tang screw to meet the trigger plate, bevel that hole for the tang screw, then drill and tap the trigger plate to accept the tang screw.
Don't mean no disrespect,, You should be able to handle it,, I just wanted to give ya a heads up.
p.s. You should at least get the TOW catalog, they have "actual size" photos of many-many available parts,, that is useful in so many ways when trying to make or fit things we use for these guns
