I have a stock 1963 hardtop with a 260 V8 and would like some opinions on what would be good replacement shocks.

Garbriel? KYB? Monroe?

My car presently has MOPAR shocks:

O'Reilly auto parts has Monroe-Matic shocks for $19.99 / 20.99 front and rear.

They have KYB GR2/Excel G shocks for $52.21 / 29.99 front and rear.

Gabrielle has something called "Classic" that is made for older cars.

Would new lower front shock mounts be most likely necessary? They are $29.99 each at Dearborn Classics:
