American Prime Manufacturing Inc. offers a Stainless Steel advance unit at a very reasonable price. It is American made and assembles and it is a very high quality unit fro severe duty use Contact us at www.americanprimemfginc.com. -1 Permalink Larry Nelson July 17, 2018 19:40 Hello Ben. 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.
