Hey buddy, i will take some foto's of the undercarriage of my U12 Atessa for you, i will post them up soon. if u r considering doing a conversion on a pintara, u will find it cheaper to buy and import an original bluebird, i investigated doing the conversion myself and with all the work involved and slightly different measurements, it was about 20k cheaper to buy the original car.
when i put the pics up, hope the help with ur decision
