Thank you for offering this unit to Dyna-S customers. If anything like the unit Rivera Primo offered, this will be a quality item to replace all old, worn advancers and for new builds as well. Thank you. 0 Permalink Ben Kudon July 17, 2018 21:03 Hi Larry, It is in fact identical to the RP unit except that it is now made by and branded American Prime Mfg and it is actually a bit better quality as I have taken pains to make the new tooling better.
