I have the standard size full power mirrors with heater on my truck and I would love to go to the large extendable towing style with the same options that I have now plus light. Is this an easy swap? I hope to find them reasonable somewhere other than the dealership.

I recently added the tow mirrors on my '03 1500hd and when I was doing research I found a site that said these mirrors would directly fit the '99 nbs all the way to the '07s the only difference I know is the wiring on the '02 and older are different compared to the '03 and ups. So you will probably have to do some splicing to retain the power mirrors and heat options, heres a link that gives instructions for installation on an '02 and older

Hope this helps Danny

Last year i installed a pair of the extendable mirrors on my bosses 2001 2500HD 6.6 by getting a pair of aftermarket power window switches from NAPA and wiring them in, the mirrors i got from Ebay, not easy to do but it was a clean mod by the time I was done and each can be operated independantly.
