You can use the stock trans crossmember. I have a 4l80e and just had to slide the xmember back like a good inch or two and redrilled the 4 holes on the frame.

+1, Also if you are using the Dirty Dingo adapter mounts you may be able to use the factory location for the crossmember. I spoke with one the the Dirty Dingo guys and he informed me if using the mounts for your model truck truck they supply (part number DD-2550C, my truck is the same as yours) you can position the engine to keep your factory transmission crossmember location. In the end, the best result is to put the engine in the best location possible, if you have to redrill holes, its no big deal, do what works best. Also, is the transmission you are using with the new 5.3 or an older 4L60 or newer one that was mated with the engine? If it is an older 4L60 there is a .400" difference between the 2 and it will require a spacer that is easily aquireable and/or can also be made if you have some metal fabrication skills. Good luck with your swap. I have one going on right now on my 94' Silverado.

For simplicity of driveline, your best bet is to get the engine settled in place, bolt in the trans mount, and then snug down the engine mounts. Otherwise you have to start playing with driveshaft lengths.

I agree most with Wagonbacker, using dirty dingo mounts should allow you to place the engine where the factory transmission placement belongs requiring no driveshaft mods. When you start messing with the drive shaft you can miscalculate the pinion angle or the correct amount of length needed. A couple of inches too short or long can result in either the drive shaft falling off or bending in an instance of great suspension travel also damaging the trans. I have seen this more often in the four wheeling world but never in everyday use if you do not tow on a regular basis. The dirty dingo mounts as mentioned above allow a total of 3" of travel, 1 and 1/2 foward and backwards. This should make factory line up as you started with. If it doesn't, just post what you have and go from there. Drilling new holes is no big deal, just as long as you are not moving far from what you started and wanting to keep your factory drive shaft.
