1977 chinook distributor cap and carb
 

I recently picked up a 1977 toyota chinook. Managed to fix quite a few issues (it sat for 5+ years), and it is now running / idling fine.

1) The distributor cap on the vehicle has 2 screws to hold it on, every replacement I have seen has clips. (1st photo is my cap, 2nd is replacement) Any idea where I can find a replacement or find some clips I can screw on to use the replacement?

2) I am assuming from back to front on the passenger side of the carb, screw 1 is fast idle, screw 2 is idle, and screw 3 is air/fuel. What is the factory setting for the fuel air mixture, as I inadvertently messed with it.

Thanks in advance, and sorry if these are stupid questions, searched the forum and googled for an answer before I asked.

Someone might have changed the dist, so try asking for a newer style cap.

good call, i just checked the newer style caps and it looks like a match, will take it down to make sure. I did the stupid thing and assumed that when the previous owner said "everything is original", they meant it.

The cap on my 1980 20r has the 2 screws also. I bought the truck 4 or 5 years ago and changed the cap right after I bought it. I think it is the original motor and distributor, Napa had the right part.
