Why wont a Prelude B20A rear transmission mount bracket work?

It's been so long I dont remember what the issue is and I only have prelude brackets. So I'm really hoping it can be easily solved by adding a spacer or similar.

The spacer idea will probably work. If it's anything like when I put the B20A in my 2g, the rear bracket was about 4 inches higher than the mount. You'll need a pretty big spacer. Luckily I had an Accord mount that worked for me.

Wow. I was hoping for max 1 inch difference. If the Accord bracket worked in your 2g then it should be the same 4 inch gap on the 3g. Crap..

Your best bet might be to source a used Accord bracket. New-Zealand time :D
