TCI will be on lhs of engine bay, forward of coil. If it works and mpg is acceptable then leave for now. A
Advance curve probably not far off because both are around 9:1 compression. DF has very mild cam timing though, might be worth searching for a proper DF one but they were the earliest wbx.

I have a dizzy that looks like that but the code indicates its not from a t25 (can't remember I will dig it out) have a clean and read the code off it is the best way to be sure.
Final update .readjusted tappets as per solid 6 thou engine stone cold , fitted new distributor cap and rotor arm,engine running much better than before and doesn't sound like a man running behind shaking a tin of ball bearings !
i have located a good distributor off an early df,watch this space .
