Me too! 
Yes have found an oil pump in good working condition from the junkyard.
It has been cleaned, checked and fitted.
The oil reservoir bottle was also repaired and checked for any leaks and now the setup is operational.
For the wiring harness there were two brackets on the frame to hold the wiring harness.
For the remaining wiring harness I used these small plastic ties.
Wiring has been neatly secured along with the frame with these plastic ties.

As far as the headlamp case is concerned then I plan to use a bigger headlamp in it.
We have been testing various headlamps and its original one looks too small because of the bigger speedometer and indicators in place.
The best combination was made with the CD 100 headlamp.
Gives a muscular front look to the bike.
Thanks buddy!
The tachometer will work with the gearbox shaft.
There is space present at the back of the engine block.
Got the speedometer for 1k.
BTW let me know if you know some one who is having the "Deluxe" emblems for the side covers.
Naah, there was ample space on the top of the air filter assy to pass the cable of the tachometer.
Have a look.

Tachometer is operational.
