Straightliner I am inclined to think that your front sway bar area may not need to be modified if it is tucked behind the front facia first and the rear set in, looks like minimal shaping otherwise looks like the wheels are pretty much inline in the front other wise a pan chop before the seat dimples but behind the trans cross member could be just enough to do justice, at least my pieces of grumpy lump will be fitted to the Monza frame to better fit my body. I saw a proposed 73 Vega kit coming out somewhere, Lawson's I believe that would be a true 73 tube job frame I would hope, there was some guys over on the Vega pinto post talking about a 73 Vega kit at some point to that was produced way way back but I don't think it was an AMT kit
