Mexican Open Air folding roof top

Hi
After hours of research,Samba,etc I have been looking for any information on Mexican Open Air/Transforma open air beetle rollback roof to see if the kit can be sourced and if it will fill the existing hole to take place of the ugly roof I have.
1st and 2nd pictures is what I want to fit on 3rd and 4th pictures,
Any recommendations,information or help greatly appreciated

Any help with this appreciated,I have seen similar Britax roll back roofs but can't find suppliers of any tidy looking rail sliding roofs only clip on
