4x4 frame holes

I have a 1969 3/4 ton 4x4 frame I am converting from stick to 350/350/205 auto and the holes in the frame are not there as they did not put autos in 4x4 that year. Does anybody have a 70-72 frame they can take detailed pics of to correctly locate the holes for the transfercase crossmember. thanks

Re: 4x4 frame holes

I took the rivets out of the brackets that go to the top rail and removed them from the transfer case member. This makes it much easier to install and remove. Just replace the rivets later with grade 8 bolts. Those top rail holes are a beotch to drill out and get right. Not sure if they are really necessary as I have run without them on my Blazer for quite some time.(went thru the Rubicon without them) I think the only way to drill them is a very long bit going through the bottom holes to the top using the bracket as a guide. But yeah...just drill-em.
