dx engine on webber 40's, does the dizzy need changing???

Hi, I have stripped my dx engine down for a full rebuild and have brought a set of webber 40's.  I have all the rebuild kits, manifolds etc, but can someone tell me if the dizzy needs chaning from one of a polo, if so, what year, part number etc?  

Also, can someone tell me what I need to do for fueling??  I have heard that I need to fit a pressure regulator as the presure from the pump is too high??  Im new to carbs, so need a bit of help.

Thanks, Joe

no it'll be ok, still a vacuum advance unit. leave all your old ignition bits in there and job done!
