ok ok, should be a 27 spline 203 to 205. that should get you started.

thanks for the help. One more thing. Is there a differance in a chevy and a ford 205? I want to run a driverside drop, but I wasn't sure if they bolted up differntly.

Ford 205 has a 31 spline input, not gonna matchup with your tranny. U can mount a divorced ford 205 behind your factory tranny and t-case and have a doubler.

I was talking about using a 203 chevy front to a ford 205 back for a doubler, or sould I use a 300 with a flip kit instead of the 205?

the way these doubler kits are made today, u can use ford with chevy like u want to do. the problem u will have is the VSS, since the 4L60E is computer controlled. Maybe just as easy to use a 241/241 or 231/241 or 231/241 doubler from DD Machine so u can have ur VSS hoodup pretty simple. What is this setup going in?

Its going in ext. cab nissan. I'm going to send computer to speed and performance to have the wiring harness cut down, and reprogramed to make it a stand alone system. So I'll have to ask them if I'll need the sensors for the transfer. Thanks for the help guys.

Pretty sure u need the VSS for the tranny, unless u can get some kind of manual valve body, never got a straight answer on that.

Having smoked 2 4L60E's myself, and seen ~6 or 7 friends smoke their's, I'd build that trans stout before I started into a doubler behind it.

I know a guy running a 4L60E with a 231/231 behind it and he loves it, but he's only on 33's.

I talked to advanced adapters today. They said you have to run the speed sensor. So I think I'm going to run the 241. How long would the 241/241 be?

There is a thread on here about the DD Machine double using the 231 and the 241 matched with other cases, search it out. It has lots of good info on it and lots of pics to give u some ideas.
