Jigga89SEI, I think you can use the stock axles of Accord, but you need to cut and
balance the passenger side axle, please read here:

So you just need to measure and cut-balance your stock passenger side axle...
For wiring harness I strongly recomend use a stand alone ECU like POWER FC ( APEXI)
or DFI, or AEM............solves a lot of problems for the swap.
The shift linkage I think is just shortened and you must cut and weld your stock
shift-linkage ..........and many peaple have done this without use place racing's
shift linkage(who has done the same job, shortened your core-stock shift-linkage).
For power steering bracket and A/C bracket i don't know but maybe you must use the
new 'b' series compressors together with the new engine.
The only real problem are the mounts, so if there are still people in the site who care about this swap i thing the best thing is to copy place racing mounts in
one machine shop.
For TURBO-NITRO route, old A20-B20a are nice engines and i don't think that is
real need of a new B series engine swap.
For N/A power newer B series are much better because of the Huge aftermarket suport
and the availiability of parts....
