Ruger SA Ejector Rod Housing Question

[Rocdoc]

Cannot find the answer in my reference material: Is ERH the same for all? Large, medium, small cylinder frame SAs? Shop Ruger has a 4" steel version says fits Blackhawks, Vaqueros, no mention of SS6, I want to swap in for Aluminum on a SS6.

Edit: answer is no, diameter different

Answer is Yes, they will work. I've replaced all my single six ERHs with steel ones. There haven't been any old model single six steel ERHs available for years. So I tried the Blackhawk/Vaq/SBH and they work.

I couldn't find ERHs on shop Ruger. Where did you get the diameter is different? They're not.
