D30 swaped in in less than a day things went really smooth up til the trans crossmember.
There is no room for it I have some 2" square tubing holding it up for the moment, but I know that cant stay, Has anyone ran into this before? but between my long arms, t-case and front driveshaft, theres no room on the left, and with the 2 cats on the right space is limited, I'll post up some pics soon as I get them off the camera, but this is gonna have to be some tricked out crossmember.

 

as seen below I some how ran out of room under there.

I ran a d30 set up on my truck and didn't have any issues. What arms are you running?

 

I have Rusty's off road high clearence arms, I'm about 2" past where the skyjacker extended arms were on the ttb, and also pusher the d30 forward about 2 1/2". I could have prolly moved the arms back another inch with out any issue as far as that part. I'm thinking mayby an "X" type cross member with a drive shaft loop in it to clear the front drive shaft, and that should give me enuf strength to hold every thing up where it needs to be.
