Rich mans method Is to steam first, then use Rachet straps hooked around lower door hinge . I have done some tops that even two people could barely hook . Works better than Superman

Stay away from harbor freight, unless you like cheap useless tools , All you need is a 4x4 and a few lag bolts .

I like elmers glue . It takes a while to dry .works great

EBay

The Texas shops selling on eBay are destroying the upholstery business, lowballing ( example 2009 Chevy truck seat bottom in leather for 60 bucks ) their poor quality products and their products are made in Mexico . Once over the boarder they sew tags saying made in America and title their stores USA this or US that plus they have 8 eBay stores under different names to drive competitors out
Best of luck getting a fair price on what your works worth
