Joe,
1" SU 'UBA' ('VOM') carbs were fitted to late 1934 to 1938 Morris 8 Pre-Series / Series I and Series II Saloons, Two-Seaters and Tourers. Note that these carbs have a vertical inlet manifold stud flange so you'll need an adapter plate to attach to an A7 horizontal stud flange.
A slightly easier option though much more expensive is to look out for an SU 'OM' 1" carb as these have a horizontal inlet manifold stud flange - they were fitted to pre 1934 Morris Minors and their 1930's similar engined MG Sports Cars and therefore carry a much higher premium and are more scarce.
Morris 8 SU's frequently turn up on ebay at reasonable prices.
If you're wanting a slightly larger throttle diameter then the SU H1 - 1.125" fitted to the 1939 to 1948 Morris 8 Series E would be a good choice - these H1's also have the advantage of a suction piston damper which the earlier 'UBA' ('VOM') carbs don't have. As with the earlier Morris 8 'UBA' ('VOM') carbs the H1's have a vertical inlet manifold stud flange. These too turn up quite frequently on ebay at reasonable prices.
There's also a 1.125" SU downdraught carb used on a 1946 to 1948 Wolseley 8, but these are quite rare as are the cars.
Hope this is of some help.
Jeff.
