The parts list for a GP doesn't show one. It only shows the tail light lenz gasket (22083001)
IMO. The plastic tail light housing on a GP never did look right without a shut gasket between the housing and the frame. (Innocenti were looking to cut costs wherever possible with the GP)
I used to use the tail housing shut gasket from the SX range (19983021) and, if memory serves, even these wern't a perfect fit on a GP housing. I would find it necessary to soak the gasket in hot water to stretch and relieve it until it fitted as best possible. Because the GP housing is plastic, you are limited to how much force can be applied to the fixing studs.
Fixing the gasket into its correct position and holding it there with some contact adhesive helps to prevent shrink back of the gasket after fitting.
Another option to consider would be to use some rubber "Tadpole" beading strip glued into position.

Early NO, hence not in parts book.
Late model YES, hence listed on later official dealer update lists.
If you are lucky enough to find a genuine late light to frame rubber it will have large circular holes that coincide with the change to rubber grommet light fixings, with corresponding larger holes in the back of the frame loop. The Casa /other rubbers have rectangular holes in the rubber, rather than circular.

Thanks for input.
Its been manipulated to "fit" .... Its a SIL frame and SIL rear light... So its never gonna be perfect.
Gonna buy some black edging trim and see what that looks like
My last SIL one fitted better!!
