727 to getrag swap 2x4

[pepecat]

Anyone EVER do this swap?? I have all the parts HOWEVER I have run into an unexpected hurdle. the 4x4 auto and manual and the 2x4 manual seem to have a bigger tunnel for the trans... a big squared off hump in the middle of the floor and mine is not as large. has anyone tried to stuff a getrag in the space of a 2x4 auto tunnel?? if so, how did the fit and finish look at the base of the shifter, / floor? I have the shifter boot assy and all.

well you can alway cut a tunnel out of the manual truck < & weld it in ?

maybe it will squeeze in ? call me !

So what did you come up with? Are you gonna leave it, or swap in a hump?

I did a 518 to Getrag swap, and had no problem with floorboard clearance.

Don't know if there is any difference between 89 and 93, though. For the shifter,

I just made a hole with an air-powered cut-off wheel. Don't forget to include a

2-piece driveshaft in your plans.

His truck already has a 2 piece shaft, the 727 is just as short as the Getrag.

Or maybe you could just use the BFH on the floorboard to make some room. Getrag and 3. 07's sweet!!!!

Is the tunnel sizing a diesel only issue? I have been helping a friend with a 86' W150 automatic swap to a 87' W250 manual, I called him after reading this and he swears there is no difference in the tunnels. I'll have to confirm myself of course, just the way I am...

I believe the W trucks all have the big tunnel to accomodate the t-case shifter. If his truck were a W, it wouldn't be a problem. The tunnel in Pepe's truck looks like a car tunnel, gently sloping and close to the trans.

They are both W's, I'll have to give a look see compared to my D250 or D350, I never really paid attention before reading this. Good to know. Pepecat, have you called around to any salvage yards?

I've done a lot of calling with no luck, and most military surplus places are out as well (from the m880)... I am waiting on a call back from a guy who is parting out a 1977 w150 truck... that should be the bolt on hump plate. The w's all have big humps for the t-case... mysteryman said the 2x4's with the a518 have a large hump as well. looks like I have the only possible setup that has a small hump... hey biglbert ... I may have to use the bhf for a temp install,,, it will all be cut out anyway when I swap in the big hump...
