You will require a large spline boss for a '92 car, VW went from small to large spline across the range in 1990. Actually, all they did was to fit a sleeve to the small spline steering column which is removable with a puller. A Momo wheel will sit slightly closer to you but it will only be 'slightly'.
An answer might be having a spacer fitted between the wheel and the boss if it really bugs you. If you do an e-bay search for 'Momo steering wheel boss kit spacer' you will find lots in different thicknesses.
