I think I'm going to buy the set of 4 shock absorbers for front and rear. Any recommendation when change the rear shock absorbers? is necessary to unmount the Leaf Springs to change the rear shocks?I have KYB Gas-A-Just shocks on the front of my 1978 NYB. What a difference they made. I highly recommend the Gas-A-Just shock. I have factory Air Ride on the rear of my NYB.
These guys have them on sale for $148 total for all 4 plus a $40 rebate. Advance Auto Parts want $70 a piece for the same part number.
