3rd Gen T-Top Converstion

Hey all I'm looking into this 3rd gen non T-Top but have been in love wiht the T-Tops for awhile now, how easy owuld it be to do a T-Top converstion on a 3rd gen and should my local bodyshop be able to do it, he does restorations etc..so I'm pretty sure it wouldn't be much for him to do. I'm also doing an engine swap because the current engine has a thrown rod so I need it to be running sometime here.

I'm thinking about getting a T-Top off a third gen from DavidT's up north from me and maybe picking up missing parts if it is doable.

Thanks
