Keith - can you share where or how you acquired your ARC version? I'm looking for a 90+" ARC Sportster Y but only have found the PAM 97" ARF. PAM has not been responsive with selling me an ARC version. I will build from kits or scratch build but have only found AMA / Haffke plans from the 70s and I'm not sure about these foam core kits from Devine.
thanks - Jack
