UMM, I know that they dont bolt up to the 240sx mounting bracket that is why i got the RB25 mount brackets so i can do the swap for $260(motor and transmission) and i dont want to pay $600 for the mount kit that you sell.

I not sure what mount kit your using but im using the sykoperformance that uses the stock r33 transmission mount, If your motor did not come with one just find a auto KA cross member

Im using the zerolift, which i think is the improved version of the sykoperformance.So basically im looking for the r33 transmission mount but cant find one. and what do you mean by auto KA crossmember?

If you just need the trans mount go get a Nismo one from a dealer. I'm pretty sure they're all the same.

The mounts are not even close in design Zero lift that makes the mounts is near me, I know the people who designed the kit they use some bracket style mounts. You're thikning of Rucas rb mounts zerolift is based off that kit not syko. I mean use the transmission mount from a KA automatic car not the manual transmission mount.

I totally misread what you wrote , your just looking for a rb25 transmission mount not the bracket! Duh! You can just buy them from most nissan shops.

They have no problem taking your money and then not answering emails after they've back ordered your part for 6 months. I wouldn't do business with them.

Look in the stickies, theres a thread with cross refrenced parts to something thats USDM available. I think the rb25 shares the rubber part of the mount with the z32.

Next time be a little clearer and dont bit some ones head off when they try to help you. Mckinny/Fast Datsun is a help to the rb swap community.

And the zero lift mounts aren't related at all to the syko FYI, completely different styles. The ZL mounts were actually designed from scratch.
