2 more gt's for me

I went to look at two gt's last night. I don't think I have room for the "spare parts car" but they are a package.The other has an 88 SVT turbo charged engine installed and 5 speed tranny but all the rest of the turbo and radiator are not installed.Also has Steinmetz flares,air dam,and side skirts"they are not installed"look new.I have a lot of work ahead of me but I think it is worth it for $800.00.Iwas wondering if it is common to put the SVT motor in a gt.If so how hard is it to finish the turbo and radiator.I was also wondering how much it usually costs to have the flares installed.Any comments might help. Thanks Tim
