What is the length of stock brake lines?

Does anyone know what the length of the stock brake lines on a '99 V6 4x4 is?
I ordered and received some new SS brake lines that are supposed to be +3" over stock, but they are shorter than what's currently on my truck. The SS measure 19" and my truck has what seems like 21".

I have a 1.5" lift and it's possible the prior owner put extended lines on, but I doubt it.

I ordered the SS lines to do the Big Brake Mod tomorrow, but I don't want to take everything apart, if these aren't going to be long enough. It's hard to get an accurate measure of what's currently on my truck.

 

I bought mine from the group buy here, and I have 3 inches of lift . I still have slack.

The guy who does the group buy can overnight them... I had to do that.

 

Well, I already bought the brake lines. I'm just trying to figure out if either:

1. I was sent the wrong brake lines

or

2. I was sent the right brake lines, and the lines I currently have on my truck are +4" over stock length.

The ones I received are shorter than the ones on my truck.

 

well, i called a few service departments and got independent confirmations of 22"- 23". Since I measured roughly about 22" on my truck, I'm guessing they are stock.
And I was sent the wrong lines.
