Dont worry about the balance pipe. I have been advised by some of the old school guys that with twin carbs like the IDFs (1 carb per cylinder basically) you need to cut a little port between the two cylinders to make the car idle better and have smoother driviability. But mine idled at 600rpm without issues. Never saw the point.
Its looking good!!!
I was also wondering about the grease nipple, thinking that I have never seen any nipples there.... good idea.
If you want to keep the nipple clean (so you dont get sand and dirt in it, the easies way (if you dont find grommets) is to leave a dab of grease over it after lubrication, then when you need to grease it next time, just wipe the grease and dirt off and you have a clean nipple.
I like nipples
