Here's a grille still attached to what looks like a pretty nice 71GS 350 for just $5600. http://adcache.collectorcartraderonline.com/10/3/8/64720838.htm I also stumbled across this 70GS for $2000. Wonder if it has a grille. http://www.2see.com/DGKY001/
The 71 has been for sale for quite some time. I thought about checking into it later in the spring. Anyone know anything about it?
