Injector sizes / Rover 3.5 efi conversion

["Niinikoski, Juha" <Juha.Niinikoski@mikrolog.fi>]

I managed to get 17087162   0269JSS throttle body (probably from 350
engine). I found that there are different # injectors in each throat.

IAC side is 5235342*RPD
other side  5235134*RPD

Is this normal. What engine / configuration is equipped with different size
injectors if any ?

I also managed to get
two pieces 5235206*RPD injectors
and 
two pieces 5235203*RPD injectors

>From what engine are these ?
Are there somewhere in the net data about GM throttle body injectors ?
