s14 vlsd into s13 school me, I do know something

I was able to find an s14 diff I’m thinking of putting in my s13. I just need to clear a couple things up first.

I know I need to swap the covers, easy.

Now if I can’t get s14 bolts this becomes the tricky part. I know I need longer bolts. 90mm 12x1.25 and washers. Now I also need either a rubber w/ metal sleeve or solid metal collar to go over the bolt in the larger hole’s of the s14 diff. Does anyone know the ID of the s14 diff mounting holes? I’m having trouble finding that information. Has anyone made these collars before? I called nissan and they don’t have any parts. And I didn’t have any luck calling yards.

That is what I want to make at work but I don’t have a diff to measure with.

Thanks in advance

I have an S13 cover and need an S14 cover if you want to straight up swap, or just sell me the S14 one (if its the one with cooling fins.)
