I can get hold of a complete Celica interior. Don't need the back seat tho !!
Anyone intested in buying ? I don't know about shipping but I can ask around.

100 euro's +shipping

Slightly related to this - do you know if anyone makes seat brackets for the Starlet?

Are you having custom mounts made up for those Celica seats?

Yes,..I think raceland makes brackets for starlets. But don't know if the celica seats will fit tho, but I'll try to make a custum one for them.
The rear seat won't fit I think that's why Í wanna sell him!!

get an upholsterer to put the celicas cover on your seat frame after modding the cover a bit. Keep it matching.
