Default Rear motor mount bolt tightness

I am replacing the stock rear motor mount rubber and am wondering how tight to tighten 3 Castle nuts. Searched but just cant seam to find the right search terms to find the answer. Using Snyder's rubber and original bolts. If I align cotter pin hole with castle nut ,not very tight. If I tighten to compress to spacer nut is past cotter pin hole. What is the correct tightness?

There are sleeves that limit the amount of tightening.

If the nuts are bottomed out and beyond the cotter pin holes, something is incorrect. If possible, match everything to original parts.

Those rubbers are there to absorb vibrations, too tight they can't accomplish their job.

The sleeves can be different lengths. Check the length by inserting the sleeves in the two rubber pieces and through the frame. The sleeves should be flush with both outside surfaces of the rubber pieces, or very close to flush. If not, order new sleeves. Or you can make new sleeves by cutting pieces of the right size steel tubing. It can also be that the bolts are too long. Ford probably used bolts that were machined to fit and the ones from the parts suppliers may just be off-the-shelf bolts. If you do indeed have original bolts then they should be the correct length. The new rubber pieces could also be the wrong thickness. If everything seems right, drill new cotter pin holes in the bolts or use washers.
