Deepest reach welding vise grips?

Almost 16"... That's 6" closer to what I have now can we say "splits the difference" between what I bought today and what I need?
My neighbor who's been a body man for years (can't weld no more because of a pacemaker) made the same suggestion about cutting the new ones I got this morning and extending them... If I could get this guy from KY to call me back like he said he would, for his price I'd just go get that and drop it off at the paint place... I was all ready to go straight from work Friday but never got the call he promised me
