03 GMC Tow mirror fitment

[sparky1562]

What year Chevy tow mirrors fit the 03 GMC?
Looking for power operated manual extend with turn signals for my 03 GMC. When I search Chevy I find them to fit 03-06 Silveradoes, but cant seem to find them listing the 03 GMC.

Will the GM73EL-S and GM73ER-S fit my 03 GMC???

Getting tired of reading and searching. Looking at power adjust/manual telescopic/heated/turn signals'

1aauto has them for $ 309.95 pair. Who makes these??
K-source has them for $300 pair (amazon). have not seen anyone comment on K-source?
RPRU has them for $ 349.95 pair. Are these really any better?
Kool Vue (discount mirror) has them for $ 191.83 shipped. Are these the same quality as the $ 300 mirrors???
