New Kid in Seattle w/ ???

[70guy]

Howdie to all. Well, I'm hoping I've figured out how to post a thread. 1st thanks to KRUE & ROD for helping w/ some questions right outta the gate. I've confirmed w/ Rod my GMC truck IS a 70', 3/4 ton from Fremont, OH. I found it in 99 & snapped it right up (after a month of coaxing its previous owner). I'm putting up a few pics & I got it the way it is in the pics- it used to be met green. Love the truck; runs great, no rust, no leaks & no errors mostly. BUT, if anyone knows; were all GMCs of my year fitted with dual headlights?? Mine has single headlights. Found this site trying to track down decoding for the VIN before I start ordering stuff; I'm getting ready to start some detailing to it, mats, door panels, windsheild & other odds & ends, but also wanted to put a 'GMC' grille back on it. Can that be done without changing the whole grille out to dual headlight system?? Finding I'm pretty ignorant about all the subtle & not so subtle differences btwn Chevys & GMCs & glad I found this site. I also belong to the 'Old Plymouth Owners Club'. I did a restore (not frame off) on my 51' Plym Savoy Suburban Wgn in 05'/06' that turned out nice & just bought a very clean 67' Fiat 1500 Cabriolet, all stock/no rust, that I'm fixin to go thru - it sat in a garage the last 10-12 yrs. GuessI just like the old ones. Appreciate if anyone can help educate me re the headlight stuff. Thanks - Later.
