Re: cummins conversion quick question

what tranny are you putting behind the cummins? I have just finally started to drive my swap some here latley. I found info over on the 4bt swap site. I used a ford truck master made a wedge for the firewall then the slave was for the dodge tranny that my 6bt came with. Mated the slave and master with a explorer clutch hose. Hope this helps

Re: cummins conversion quick question

When I put my cummins in my 79 Cherokee with the g360 I used a mid 80's ford 350 master cylinder and the slave for the getrag. I bought some clutch hydraulic fittings and braded line from summit. Works great but now it's going in my suburban with an auto. Check on my website in my sig and go to vehicles then "the jeep". There may be some pics towards the end.
