I need a 85 AMM for a 244 with a jetronic, and I might have access to a 89 or 92, They don't look the same, they don't have the mix screw, but the connector is similar. Would either of those work?

 

No. Check the last 3 digits of the Bosch part number. Your car is LH2.2 and has an 007 AMM. The 89 will be an 016 amm. The 92 will either be an 016 or whatever LH3.1 was...They can not be interchanged and will fry when you turn the key on.

 

thanks dude, so 85-88 then?

 

Yes. 85-89 240's...except the 85 turbo car. Also, 85-88 n/a 740's and 85-89 turbo 740's.
