I have a slightly different perspective. 99.9999% of all frankens I have seen, recently Rolex Addict built a 1680 with a gen 1570, but most all are gen parts with rep parts and an ETA, or like my 1601, 97.34567% GEN with a ETA. It seems to me a big waste of time and effort to use a 3135 for a rep build. If it were me, and its NOT, I would flip that 3135 for gen sub parts and build a rep thats ALL gen from outside with a ETA engine vs. rep parts franken with a 3135 inside. If you are getting it at good of a price, consider flipping it instead.
PM correctime he is looking for a 3135.
