Any 5.3 Conversions out there w/4x4...?
If so, I have a question regarding the usage of the original transmission support mount which also cradled the NP208 case.....? I am getting close to installation and was wondering if anyone has done this already and what you used to cradle both the new 4L60/65e and the t-case... If I can still use the original then great - no money wasted... If you found you could not use it, then please list what or how you resolved it.. Thanks in advance..
- A.J.

Re: Any 5.3 Conversions out there w/4x4...?
Nevermind I relooked at your build thread. NV4500 so no trans issues. Do you just have engine mounts and no crossmember?
72truckman, Can I see your engine mounting/crossmember? Are you running a lift? Any driveshaft/transmission pan interferance issues? I am in the middle of an NP205/4L60 5.3 swap on a stock height Jimmy. I believe I have the differential/crossmember interferance taken care of. I need to test fit then powdercoat the crossmember and then tackle modifying the tranny pan. Interested in how you handled your installation.

ON my 4l60e i used the original crossmember and built it up with some sq tubing and then used the factory 4l60e rubber mount.
