Swapping s13 R200 into my s14

[usdmps13]

HI,

Ran into a problem while trying to put my s13 r200 with s15 helical into my s14. Where the two bolts in front that go into the subframe the holes on my s14 R200 have bigger holes with bushings. It's been a while since i pulled the s13 diff out and i can't remember if it had bushings on either top or bottom of diff. 2 questions.....Are there bushings for the s13? If not can I just use my s14 bolts to bolt up the diff...they seem to fit in the holes pretty good, but I'm not sure about the length because the S14 seems thicker where the bolts go through...so i may need shorter bolts?

Thank you in advance.

Ok I found the bolts i had them in a box full of crap in my garage, they are a lot shorter...now i just need to know if there are any bushings that go with them...all that's on there now is a washer and a lock washer.
