help from kr 16v/r1 carbs converts

Looking for some info as carrying out this conversion just now.

Wheres the best place to get filter for carbs like the ones on tuk customs white mk1?

What do you do about crankcase breather? Can you just put small filter onto it?

If you run R1 carbs i take it your using fuel pump, if so do you also use R1 fuel pump relay or what have you got running pump?

And last but not least, do you advise getting external oil cooler or just stick with the one thats on?

Thanks in advance.

Also, does any one have crankshaft pulley with out power steering pulley on it that you want to sell?

Any one?
