No worries Ed, the stem is an ETA part which screws onto the rep/gen Omega crown, also be aware that when doing any crown/tube swap to gen you will need to order both the crown and the tube as gen to rep parts will rarely be compatible.
The gen PO tube is press fitted as is the gen SMP tube. The main problem will be that the hole in the case being the wrong diameter, I was fortunate when doing my SMP tube/crown swap as it was quite a tight fit but I added some adhesive to be sure. Looking forward to hearing how close the PO is before I rip out the rep tube
Hey Ed, Im not sure what you mean but I was referring to Eric L. who may have shortened his ETA stem too much. Im not sure about the lite version but ETA stems are pretty easy to get.
I would be interested to hear how you go, I bought them from cousins when the rep first came out and have not bothered to fit them yet. My part numbers are 069ST42184 (crown) and 090ST1232 (tube) but the tube container has x12870 hand written on the top.
I probably should do it as it made a huge difference to the feel of my SMP.
