Replace Plastic Mount with Metal?

I have a broken DA 55-300mm with the metal mount. I want to replace the lens, and wondered whether I could by the cheaper DAL 55-300mm and then replace it's plastic mount with the metal mount from my busted DA 55-300.

Is that possible?

I looked at doing that with a DA L 18-55 and a broken DA II 18-55. I got as far as removing the mount, but it didn't look like I could just swap them - the body for the plastic mount had additional metal connections to make up for the mount not being conductive. Someone else may have been more determined and gotten further than me.

If the durability of the plastic mount is worrying you, I don't think I have read any reports of plastic mounts failing. It's a 'problem' that gets discussed a lot, but never seems to actually happen. On the down side, IIRC, the DA L 55-300 lacks quick-shift focus capability.

I've seen it done by some folks but haven't seen a step-by-step to know how complicated or simple the process would be.

Probably not worth the time & effort. I think the "fragility" of the plastic mount is way overstated. As Thoog stated, the lack of quickshift on the DA L would probably be more of a concern.

I have a friend who had the DA L 55-300 mounted on his K-x, hanging on his neck with the neck strap. When he saw his little boy felt by his side, and by reaction he bent down quickly to catch his son and did not think about the camera. The lens hit hard on the pavement and broke right off the camera, leaving the plastic mount still stayed on the camera mount. When got home, he took the broken lens mount off to inspect the camera mount and found no sight of damage at all. Since then he liked the plastic mounts more than the metal ones.

I was nosy about this subject a while ago so posed the question - only one person managed to break a plastic mount in that thread.

I think the adage applies here "if it aint broke, don't fix it", in other words until, or if the plastic mount gives problems, leave well alone.

Would having the original lens repaired, not be an option?
