We have my truck tore down and were wondering if new motor mounts is all we need or if we have to have both frame mounts as well. Truck is a 2006 NBS RCSB. Thanks!

Yes the 2WD V6 Passenger side motor mount WILL WORK. I will attempt to attach a pic of the old ones I removed from the 2WD truck and the new one I bought. the only reason why I had to buy a new one was because I broke the bolts inside the threads and did not want to have to drill them out. see for yourself. Good Luck!

Someone please correct me if you find out otherwise.
And the V8 Frame side motor mount part numbers again...

Thank you for the quick response!

Does anyone know if the v6 torque converter will work? I know it reads that a stock v8 one will on the first post but after looking for awhile I have yet to see anyone try this with the stock v6 one.

Having some issues with a "2005 they claim" Silverado harness, If anyone could take a look at this it would be very appreciated!

https://www.performancetrucks.net/fo...-v6-v8-554424/

- Edit -

Can anyone clarify if a 2006 5.3 2WD Yukon will have the same harness as a normal 4.8 / 5.3 / 6.0 07 classic 2WD Silverado?
I found one that I can buy and I think it will have all of the correct plugs (2 pin alternator since it seems that the 05 one has a 3 pin?, fan setup, etc) if they can be swapped.
I compared the vin off of a 2006 2wd SS Silverado truck and it shows to have a different part # for the harness than the 2006 Yukon one does so I was not certain.

Does anybody know how to do a throttle body bypass and what I have to do if I’m using the v6 radiator? Any help would be greatly appreciated

Alright so more ECM questions, Im doing a 2000 v6 reg cab to 6.0 lq4 with a 4l80. My ECM shows to be a 9354896, looks like it is black. The motor I'm told is out of 02 2500hd which shows having a 12200411 is this going to cause me issues?

My 2000 V6 rcsb also had the "black box" ecm. The connectors are completely different and will not work with the swap. The 0411 will work perfect with your swap, same computer I'm using now.
