Default 4L60E Linkage

Looking for some insight here on my '91 Camaro LS swap where I also swapped trans from 700R4 to 4L60E (which I thought were same housing, dimensions, etc.). Note the gap in shifting linkage. Also bracket is right up against trans pan. One more thing, as for missing neutral safety switch (NSS), my (sorta) Painless wiring harness does not come with the wiring for the NSS, but was told this (https://www.painlessperformance.com/wc/60122) can work in lieu of that, so I have that as well. Anyone have success with that alternative?

Let me add that the shift cable is the original from a '91 RS V6. The car now has an LS1 V8 w/4L60E. Would the V6 to V8 make a difference in that 3"?

Thank you pdxmotorhead...I actually think the shop that re-built the 4L60E may have put the shift cable bracket in the wrong spot! There is another mounting hole ~3" forward (towards the bell housing), so I will try to move it to see if that makes up the difference. I may need a new cable anyhow however bc this trans uses the "ball-socket" connector where the 700R4 was a nut and bolt :/

Thought I'd give you all an update...problems solved! Two issues:

(1) The shift linkage trans. shaft bracket...there are a few types offered on the 4L60E/700R4 transmissions. Many factors including (a) column shifter vs. center console shifter, (b) cable type (i.e.: bolt vs. ball/socket), and (c) header locations to name a few will determine which one you need to go with. In my case, I needed to mod it thanks to "wlink14"'s recommendation above.

(2) The shift cable mounting bracket...once again, there are a few types offered on the 4L60E/700R4 transmissions which are determined by many factors. Some are also mounted above the pan and some below...some in the middle of the pan, some at the rear of the pan. In my case, I needed to use the bracket on the right which I picked up at a junkyard for $1.33! Haha! The one on the left, which came with my 4L60E, mounts above the pan and to the rear thus causing my 3" gap issues. The one on the right mounts below and in the middle of the pan.

Thanks all!
