I just got a 1975 fastback that rides a little rough
...any bump or man hole in the road makes it sound like I just took it off a ramp.

what could it be that is causing that?
Its only the rear end. the front seems fine
....replace suspension maybe?
and if so what is my best option for a super soft suspension without any major modifications?

I've seen the Monroe shock absorbers online
is that my only option for replacing rear suspension?

I desperately need a smoother ride. Not to mention how loud and obnoxious it is.
I'm not all experienced but mechanically inclinced
any info helps on how to fix my issue?
Thanks guys

New shocks, new swaybar bushings (if you have a rear swaybar), and check the leafs where the U-bolts and plates are. I've seen several that cracked or broke leafs right at the rubber insulators (very dangerous if they come apart while driving...)

no sway bar. Should I maybe put one on?
and for smoothest ride around town what new shocks should I get?

If you can find a donor for the brackets and lower plates, yes. While the stock upgraded rear swaybar isn't particularly thick, it does help.

Just about anything is better than what are probably old and worn out units :gringreen

I'm planning air shocks for my Ghia (partly because of the onboard air system I'm using anyway) and on the Rat Snake as well (for the adjustable ride height...295/50R15's...) but I haven't kept up with what is still available that'll fit our cars.

Awesome thanks for the info man.
I've got a junkyard here in boise that as two mustang ii's.
I'll check this out and see if they have the brackets and plates
