How do i answer this....
It sounds like you have found a H#LL of a deal!!!!!!!!
As long as the cars are what/how they are represented.
You can do a trans upgrade for less than $1200 if you do it yourself, and rewire a car yourself for less money, but prob more time...
If you need advice/instructions for trans swaps they are in my signature, and if you pass on these, please tell us, (me) more so these beautiful cars can be saved!!!!!
Thank you.
