460bigblockoka

Hey guys ive just purchased an custom Aussie built OKA (forward control veh ie no bonnet)with a 460 big block and C6 from sydney and am on a mission to make her operational and drive her back to my home in Adelaide. The veh is in Melbourne and i just pulled the block out to machine new .3 over size pistons and do a reco, but on getting her out and into the light i have discovered she is cactus. I may buy a full reco long if all else fails but id have to dismantle then rebuild in situ or pay 4 a shop to remove the front diff and install her from underneath. A block or short would be ideal but ive tried all the major places! If anyone has any ideas that would be great. CHEERS
