The rules for international rallying allowed competitors to use what ever
KIND of carbs they wanted, but they had to keep the same NUMBER of carbs.
Dual-throat side-draft Webers were the hot ticket to high performance. By
going to three SUs in production, BMC's competition department could use
3 45DCOE Webers. The cars thus converted were campaigned long after
production went back to 2 carbs, even to the extent of complete rebuilds
after major accidents.
