no matter what route you take, there is going to be some fabrication involved.
what year Vega? a 74 and newer model would either need a trans with a torque arm mount on it like a Camaro or you'd need to make a mount that ties into the body somehow.
a 200-4r doesn't have the torque arm provisions or a removable tailshaft, but you could use an 82-94 or so F body tailshaft on a 700r4 and make it work by shortening the torque arm.
a 700r4 isn't physically much bigger than a TH350 or 200-4r, but it is a few inches longer if you want to use a 700r4. they all use the same driveshaft yoke. with either trans, you'd need to modify the trans crossmember because the mount is about 3" farther back from where a TH350 is.
a 700r4 has the trans cooler lines in pretty much the same location as a TH350, but the 200-4r has them moved a bit.
