Hi all,
upograding 6cyl rear to 9".
no change to the existing rear springs
last year i exchanged the front coil springs and and schocks with
heavy duty V8 springs and those red koni shocks

now that I have to get rear shocks as well, which ones will I get?

KYB Gas-A-Just Hi Pressure Gas Shocks
65-73 Rear, each..................................18125-7 39.95

or those:

KYB GR-2 Low-Pressure Gas Shocks
A low pressure gas shock perfect for those wishing to
upgrade over stock fluid filled shocks or as a companion
to radial tires. These shocks offer vastly improved ride
control without the additional harshness of the high pressure
Gas-A-Just’s.
65-73 Rear, each..................................18125-7B 21.95

or any other ideas ?

Depends on what kind of ride quality your looking for. The gas a justs seem to be the favorite around here, a little stiffer ride, while some prefer the GR-2's for a smoother ride. Then there's other higher grade shocks for performance applications, all offer mostly a stiffer ride and a higher price tag. I would probably opt for the Gas-A-Just's since your upgrading to a 9", probably for performance and higher hp applications.
