Replacement shocks

[Al 29Tudor]

Good morning,
I'd like to know what replacement shocks are available for my 29, Tudor. Currently my shocks are knock-off's designed in the 60's to look like original. They are shot so I don't have rebuildable cores.
I've read that there is a shock that will bolt up to the chassis and work well for a lot less than $1,000. The car is pretty much original and I won't use tube shocks.
Any leads on this?
Thanks,
Al
