Hello from Panama Dart 69 engine swap 5.7 Hemi

Hi to all,

I live in Panama and I own a 69 Dart with a slant 6.
I have the possibility to get a totaled 2015 Challenger with a 5.7 Hemi and 6 speed manual transmission as a donor car at a very affordable price.

I want to do a complete powertrain swap and I´ve being reading several threads about doing it and I now have some list of parts needed to start the swap.

TTI headers
midsump pan,
TTI motor mounts,
oil filter relocation kit

Beside the above parts, what else should I need to start?

Can I use the stock K-member?
I read that the 8 speed automatic transmission will need some floor and torsion bar crossmember surgery, but what about the 6 speed Manual?
What about the drive shaft? Can I use the one from the donor car?
What about the donor car brakes and suspensions? Will any of those parts fit the 69 Dart?

Can I use any of the interior, for example the dash? I´ve seen a 73 Duster with a 2014 challenger dash installed, will the 2015 dash fit the 69?

Any feedback received will be greatly appreciated.

TKS
