I would not buy an aftermarket transmission without a vacuum modulator.

Then order your kit from Dana here: http://www.pro-built.net/index.cfm?f...;productid=179

I have since talked to him a couple of times....he is a very nice, helpful guy who seems to know his sh*t!!!
When I ordered my kit from him, it was late monday afternoon.....kit was delivered on Wednesday!!!! It also made a HUGE difference in how the car felt driving....

give it a shot and keep us posted on how it goes

If done correctly it will have a metal line running up over the tranny to the firewall where it can tie in to the brake booster vacuum line. You will have to T it off. I've had one on mine for almost a year now with a built tranny and have no issues.
