Doubt replacing my T61 display

[soyroca]

Hello, I need to replace my display from my T61 (Type: 6465-CTO) Since I've failed doing a backlight replacement operation all by myself, hehe.

The broken display have this specs:
. 15.4" LCD (WSXGA+)
. Manufacturer: LTN154P2-L05
. Max. Visible Display Size: 33 cm x 21 cm (15.4")
. Picture Aspect Ratio: 16:10
. Maximum Resolution: 1680 x 1050

Also, the FRU numbers from lenovo are:
. Samsung 42X4641 R N
. LG 42T0417 R N
. LG 42T0423 R N

Having said that, I've been significantly narrowed down my options, and now a seller is asking me: "Do you have original screen part number (not IBM part number) for us? We can check for you."

So, what that it means? what is the original screen part number?

Any clue of any kind? thanks in advance.

They are talking about the LCD's manufacturers part #. For example FRU# 42T0423 is an LG-Philips LP154W02-TL10
Yours is a Samsung LTN154P2-L05

Thanks, I've missed that information.
BTW, I get that number by software, so where exactly is that number physically? I have my laptop in a half-disassembly situation.
