Hi Griezy,
There is a weber specialist in Melbourne, hit up Mr Google, can't remember off the top of my head, I got a twin throttle cable setup off him when I had webers on mine.  Len

hi guys thanks for all your replies, i'm still having trouble finding the correct cable for my twin weber set up which has a single cable linkage set up and to have a ball cup on the other end for the mark 2 escort accelerator that has the ball-cup set up



 
also what do i do with the dizzy vacuum? as the standard updraft weber has the vacuum on the base of the carbie, but these sidedrafts webers do not have any connection for the dizzy vacuum, do i use one of these split vacuum trees  https://www.ebay.com.au/itm/Classic-Performance-CLPIN38RS-Manifold-Vacuum-Tee-Fitting-Steel-3-8-NPT/232475772278?hash=item3620a2c576:g:D0wAAOSwq8FbO158 to put it on the mainfold where the brake vacuum go? would the thread fit into the thread that is already in the manifold?
 
thanks guys

.Blue slip for engine swap in nsw, personally never bother unless selling car
.Check out burtons in uk for cable, parts typically arrive within a week
. twin webers and itb's make a lot less vacuum at idle and off idle than a std carb, combined with a bigger cam the vac advance would not work as intended to advance ignition at high vac. I think this is the main reason we never bother to connect it, plus the effort and it has no performance value.
