f312 has been bought and now just a few questions...

[dorifto_s13]

hey today i bought an f312 diff from an mx13 corona, now as far as i can see i need to weld up a plate thingy where the spring is meant to sit (due to it being cut off but i did look like it was in the wrong place anyway), and if i put my whole brake setup from my ke70 onto that rear end then everything will bolt up right?
just after some clarification
ohh yeah and a 2way WOOP WOOP!!
Thanks

I doubt it will all just bolt up. But you can make anything work if you live on a farm (access to welder, grinder, tools etc).

What is the exact question again?

well i went on this website....
and i was looking for an f series that would suit my ke70, this mx13 diff (f312) is the same width as the ke70's (1410mm) and it's coil spring so i was just wondering if i just need to move the spring mount cause it's in a different position to mine but other than that from what i can see it should bolt up after that,
i just want to know if anyone knows if there is anything else i forgot?
Thanks

trailing arm mounts need to be moved.
spring seats probably are not perfect either.

its not a simple 'bolt in' job.

[Hen may possibly be a nut]

On Toymods a fella by the name of "twentyeight" put some form of F series (I think MX13) diff into his RA28. To his surprise, two of the trailing arms fitted, and two were close (from memory). So you may not have to chop everything off and start from scratch.

Sign up (if you haven't already) and look at his members ride thread, it was in there recently-ish.

Or just go out to your shed and see how things look with the F series sitting in the rear end of your car and work out what needs to be changed.
