4 speed conversion. Help or hurt value of car?

one time I had to buy 2 cars to get the one I wanted.
I went looking for a roof for my 71 dart,
found a slant six 70 dart
guy said he would only sell, if I bought both >the other a 70
4 speed dart.

after looking at it I mentioned it wasn't a real 4 speed dart and missing the bucket seats > Had bench seat
But it was a H-code.

I didn't ask, but he did come down off the price of the 2
I'm not a #'s guy,
it will still be a "Fun" car
When I restore it, get it back on the road> bangin gears.
