A500 and A518 Parasitic loss

yup made for a 200 trans. and i've seen it before and you still have to hack the stock torsion bar cross member out and a bunch of guys don't want to do that....

This is exactly right. To install an A500/A518 it is the exact same process, except US car Tool doesn't give you the loop up above. They say it isn't needed. So to install either trans the "cross member" work has to be done and is close to the same.

Now the cost of an A500 vs an 200-r4 is a different story. I was gonna go with the 200 until I couldn't find a reusable core for under $500 add on the bell housing adapter, etc. I found an a500 for $200 supposed to be rebuilt, so I am going with that.
