The pandemic has affected shipping. Couriers are not asking for signatures - they just drop the package on your porch and take off. "Porch Pirates" are taking advantage of this and stealing parcels. If possible, it's best to get the package delivered to your place of work where someone will keep an eye on it. Hard to do if you are retired.
Anyway, a carb kit is probably the cheapest way to go. Might be possible to get one in the UK if the Bedford trucks with the stovebolt engine had Rochester carbs.
