That sounds reasonable. Now if I can get the carbs I can sell them on eBay
to pay for the right SUs and manifold ;-). And have enough left to buy 2 new
cars.

>> - Modify the body near the rear carb - BFH time - New motor mounts help here.

>> - K&N airfilters with offset down 1" or UK spec air filter.
