ls1 fbody dipstick length?
 

I ordered a "fbody ls1" dipstick and the part number stamped on it is 12580830. I cant get that part number to cross reference at all.

What is the length of a ls1 stick and length to hash marks?

Where did you buy it from? That might be the subassembly number. The stick is 12551581 and the tube is 12551577.

At least with GM Parts...
Numbers found on the Part are NOT normally that Part's "Part-Number".

Wow, I had to practice saying that sentence a few times, before I could say the ending correctly.

Anyway, back to Numbers...
Example being the Numbers found cast on a LSx Cylinder-Head...
They make up a "Casting-Number", but is NOT the Part-Number.

...and by "Part-Number", I mean the Number that designates a corresponding Part for Order or Purchase.
On the GM Back-End, these Numbers have an entirely different and more complicated life of their-own.
