TRNW-2: First 10L80 no reverse

[Justin Merritt]

According to my WIT sales rep, they show 3 different plates available based
on the gm number stamped on the plate.  I could not locate the plate by
itself on repair link even when using the vin.  However, I took the gm part
number on the plate and plugged it in, and it shows my local dealership had
in stock.
