My advice is to avoid Monroe. kind of like Midas mufflers, they have a lifetime warranty and depend on you selling the vehicle before you put 40K miles on them.
I have Gabriels on my 52, got em at my local parts store. Had to order classics for the rear, he had the fronts in stock. They seem to work pretty good.
I'm putting nitrogen shocks on my 69, ended up ordering the rears from Bowtie Bits, the fronts I was able to buy Gabriels. It will be another week or so before she's back on the road, I can't work very fast or long.
