That is a coolant drain for the block.

Mostly just oil, blown out seals. I don't think anything mechanical would get damaged. I have never heard of anyone filling the diff up and driving it. No first hand reports.

If you had filled the diff to the vent hole instead of the fill hole you would have had quite a mess on your hands.

While both are called crush washers there are some that are hollow and actually crush and others that are flat soft washers that just seal crush. if that makes sense.

I suppose it could be contrived as routine maintenance, "Time to change out the zip tie"

Indeed, but is does not look as good nor is it a long term fastener with all the heat.

Jim has it correct for the spring mount. Jim also shows a small piece of safety wire to help keep the loose lever from rattling and bouncing around. That lever is for the emissions linkage.

Well I do have these in the parts cars, but I have never tested any of them. In fact I am not even sure the one in my car even works correctly. The only time the red "BRAKE" light has come on is when I set the parking brake. I have seen threads where these have been disassembled and resurrected. so it can be done as long as the insides aren't corroded too badly. Maybe JYJ's will work properly. ???

Carpartsmanual shows all the 240's were the same for these parts, 260/280 were different. There are a lot more pieces to this than you mentioned above. I may not have them all.

Sure, I'll get some pic's this evening, and email them to you. I see you have an early 70 but are requesting 71-73 parts is that correct? Dave

I do have these parts but not within the qualifier....."excelent condition"

The B transmissions should be the same length. The A 4 speed is slightly shorter, but also keep in mind the differential was moved rearward with the B thus changing the length as well.

It happens a lot more than you would think.

I found mine the same way @yarb did when I replaced my booster. I glued it back on for ease of reassembly. .

Hopefully the reaction disc is still in place inside the booster.
