Anyone local to me capable of correcting errors on a 904 race build

Well , Im pretty hesitant to allow his poor work cause more problems, just wonder what else he has done incorrectly and what parts I paid for and did not get ?

to start with, apparently the front pump was about to fall out, bolts all loose, he used a lock up style input shaft , which I questioned when it arrived and he with strong tone told me he knew more than me ..well, its not going to work
