Fantastic guys! Finding a little more modern vehicle that holds the same carrier is invaluable. You'd think it wouldn't make a huge difference but doing web searches or asking people on the phone brings up a blank silence or search if you use the 1951 Chev 3600 criteria, but saying a '68 Chevy C20 gets a completely different result. :0)
I believe I have the 4.57 gears. What kind of increase in cruising speed could I expect going with 4.10? I consider 45 mph comfortable right now and would be overjoyed to get 55 mph if possible. :0)
Thanks again. What a great reference this place is!
