The first thing to establish is what wheels are on. Generally they should be 12" as per fitted on Hillman Imps though some have 10" wheels. 12" is what they were designed for. If you have 10" wheels and suspension sag you might end up looking at new suspension too. Both the wheels run on a 4" PCD and a (check the next figure) a 63mm centrebore. If the wheel has too narrow a centrebore 20 thou or so per side at least can be taken off the projecting hub.
I haven't physically measured a 12" wheel. Jake and myself did measure a 10" wheel. The thread might be of use.

[You must be registered and logged in to see this link.]Nick did fit 12" wheels on his previously 10" shod Designer.
[You must be registered and logged in to see this link.]Not what you asked for but the best I can initially supply. One oddity I've found is that I thought all the first radial tyres were 80 profile. Hence why the profile is not quoted on early radials. It appears however that Imps ran 82 profile tyres. the size quoted is 12" 4.5 running a 155/82/12R
