cant find rear shocks for my 70 RT

[70RTSE383]

I need to get rear shocks on my 70 rt se. I quered another group and it was suggested bilstein. When ordering them I ran into a "not currently available" response. I went to Summit and ordered Koni. They came but the sleeve in the lower mount is 5/8" as advertised but the stud on my lower shock brackets is just a little big so it won't fit. Called Summit back but its unclear if other brands are any different. What specific shock do you use and is your lower mount a little larger than 5//8". I don't have a more precise way to measure as I don't have a caliper.
What the heck is the problem. It is a stock 8,75" and the car came with a 383.

I would fix the situation by pushing out the bushings  will the rubber slide over now ?

I use RockAuto for shocks, they sell a few different brands.

Does anyone make reproduction shocks? I will need shocks for a 70 TA.

[anlauto]

I think Gabriel Classics look the closest to originals, I don't think anybody is making an accurate reproduction shock.

Years ago, YO used to sell a decent shock that was similar to the originals and painted black.

I'm not sure how close to original they are. I bought mine around 20 years ago: https://www.yearone.com/Product/challenger-cuda/ng2073#prettyPhoto

I had the same problem when I bought my Konis.  I'm pretty sure the factory stud is 11/16" diameter, and I believe this is the bushing I used:

I can't confirm the diameters now as my house and garage is tented for asbestos abatement and I am locked out.  Long story.
But it should be easy to take your own measurements to confirm.
You can get these at most auto parts stores.

I know it's a pain, but once you press the old bushings out and get these in, it works really well.  It's a good fit.

I had the same problem when I bought my Konis. I'm pretty sure the factory stud is 11/32" diameter, and I believe this is the bushing I used:

I think you meant 11/16".....  11/32 is slightly smaller than 3/8".....

[rftroy]

Yes.  11/16".
Already corrected.

There shouldn't be a sleeve on the lower shock mount. just a rubber bushing that slides over the mount stud. The bushing tightens up when you tighten the nut/washer. If it has a sleeve, remove it somehow. The shock is obviously a generic fit for length only. If you check the FSM for the 1970 Dodge Challenger, the installation info and picture of the shock is on page 566.  No sleeve.
I use the KYB also. KG 4510 front KG 5512 rear

I bought and installed these without issue on my T/A.  Scuffed and painted black.  I might even drive on them some day (if I ever finish my Resto).

I only use KYB if I want a ride similar to a hardtail harley

[Montclaire]

I didn't like KYBs.  Just ordered a set of Gabriels through Rock Auto.
