Sachs-Huret derailleur

okay, now that we've beat the hacksaw conundrum into the ground, I have a serious and imminent question regarding a 1984 Peugeot mixie (P-17?) I have on the new Parks repair stand. to wit: the rear derailleur is a Sachs-Huret. I couldn't find a model number on it, just "made in France & 0984.

there are two numbers stamped on the rear 24 & 28. there are two tabs on the derailleur cage to catch the spring.

Q: how do I know which tab to use?

the Rigida rims take 27" tires. the low gear on the freewheel is 12 teeth. I am not seeing anything to correlate.

any help gratefully accepted! thanks

If your freewheel/ freehub has more than 24 teeth on the largest cog, then attach the cage to the one marked 28. Theoretically, 28 teeth is the maximum that the derailleur is designed for. In some cases, it can be possible to use the derailleur with larger cogs- but usually no more than 2 teeth more, i.e, 30 teeth maximum. If the derailleur didn't need the proprietary Huret hanger, you could get a longer claw to Aid in this project. But with Huret, this isn't possible.
