Do I have to change the frame mount brackets for the 5.9?
And what holes/ do i use to mount the trans crossmember?
Have you located a donor for the 360/A727? I would just copy what I found in the donor. There are many differences between the I6 and V8 vehicles - this has been covered a lot in previous post on this forum. You can search with Google or other online search engines and find plenty of reference material.
There are parts books on the Tom Collins sites that will confirm the difference in the frame towers for the 6 and V8. Again, find a donor for what you need online with a site like car-part.com, or advertise in the WTB forums here and at other Jeep sites. You could also look for parts cars in the for-sale forum here and at other Jeep forums.
