Sorry I couldn't update the thread last night as I was very busy with too many things yesterday. Went to see the car at night and took a couple of pictures only. Rest was taken by my mechanic. Anyways, today I will update the thread further. 
But first, replies to your queries and suggestions. 
I pointed out all the things that you have mentioned to the mechanic. As usual he told me not to worry.
The thing is, when we try to tell something to the mechanic, they kind of mind it. :S So I normally leave the work on them and money in my pocket until and unless everything is completely fine. Whether they have to do it ten times in the same amount.
But thanks for highlighting the issues. At least I'd keep them in mind while inspecting the final result. 
Yes you are right... Btw, today I got an offer of 100+ profit for the car in the condition it is atm. 
CNG kit is of Landi Renzo with 60 Kg cylinder which has been installed recently.
It was a good deal. Actually I was not the one to make the deal. I only gave my opinion about the car. The first time I saw it I said, "Wow! It is a project..." 
Thank you for the words brother. I am grateful to you for your appreciation and feelings.
Thanks. 
I do not know the Kaabli part dealer one on one. The coordination is being done by my mechanic. However I can give you the details of my mechanic who is working on this car.
The parts that I'd be getting this time and have bought in the previous years were guaranteed. Alhamdolillah most of them didn't make any trouble and a couple of times when some did, they were replaced instantly.
The car has been tuned on Petrol and CNG has not been fitted in it. That would be the last thing that would be done on it.
Thank you Sir. 
Bas yaara... Panga lenay ki aadat hai...
