The 361 bumper spikes that fit the 261

On the inside of the clutch cover under the nylon chain guide thingys there is hex cast into cover for the nuts but no holes.Drill the holes from the inside of the clutch cover 5 mm dia,put some tape on the outside or the clutch cover where the holes are going to come out this will stop ya chiping the paint or casting as you brake through,allso sit it on a bit of wood so the drill doesnt grag as ya brake through.
On the other side just remove the bumper spike and put on the new one.
If you are going to add a roller chain catcher from a 361 you will find that on the end of the rooler pin with the shoulder,you may need a small washer or two to pack the pin out a bit because it may not be long enough to locate in the hole on the other bumper spike.

BTW, that's just a ratty old worn out loop of .325 in that Poplar I think it had been filed once or twice!

In the UK Elf & Safety would have babies if they saw a chain like that. You could cut yourself with something like that.

A few years ago a group of doctors wanted to try and ban pointed kitchen knives, as they were considered too dangerous.

I kid you not. Doctors have knives out for kitchen tools | Mail Online
