If you are doing the 5 speed swap, there are 2 ways to do it. You can remove the auto tranny bracket and weld a 5 speed bracket to the car, or you can use the "no weld" method.
The CB7 tranny bracket is located on the frame in the same place as the manual tranny bracket from a CD5 or a BB4/BB6. Honda changed it from the CB7, so the CD has the bracket located in the same spot whether it is Auto or manual. The through bolt hole is slightly different, but that is it.
Using the Prelude or 1994-1997 manual transmission mount allows you to keep the auto tranny bracket and still get everything to line up correctly.
I got a good deal on the Prelude mount from TYSCB7, and it is a little better suited for the H22's power, so I bought that.
It also saves me from having to tap the tranny like you said. Since I have an H22 LSD tranny, it will just bolt right up to the tranny, and then to the car.
That is why you use the Prelude/CD Accord mount on the tranny.
As for the LX rear mount bracket, you use those because the Prelude/CD Accord manual mount wants to put the tranny several MM lower in the engine bay (not even really enough to see).
The LX mount and bracket have a slightly shorter height than the EX or auto mount and bracket, and make the installation slightly easier. You CAN use the EX mount and bracket,but you have to force it more, and it is harder on the mount.
Since my rear mount is shot anyway, I just order a new LX mount and bracket. They were cheaper anyway.
The front dogbone will get reused, and the driver's side mount will require 2 small spacers in between the engine bracket and the actual mount so that the nose of the engine drops the few MM that the other mounts have. I bought a new one of these too because all of my mounts except the dogbone are original and in dire need of replacement.
One added benefit of the "no weld" method, is that the lower positioning of the engine actually improves the driveshaft angle, making them closer to parallel with the ground. This has a side benefit of reducing torque steer.
It also allows you to take advantage of the rear motor mount insert that Prothane makes for the LX/DX and the 1994-1997 Accord, but not for the 1990-1993 EX, as well as the stronger tranny mount for the Prelude.
With the way I drive, I am going to need beefier mounts especially with the LSD and the ACT HDSS clutch and Streetlite flywheel! It should grab rather well.
The benefits probably aren't significant enough to justify rewelding the bracket on a manual car, but since it all works in my favor now anyway, I may as well make the most of it.
The engine should also not sit lower enough to where clearance is an issue. It should still be tucked up above the cross bar, but I will be sure to be aware of that.
Thanks for the concern about the weather! In the location where I am doing it, the weather has actually be very mild so far this year. I am swapping it at my parents in my home town in the desert. They have a large garage that I will be using, so it shouldn't be a problem.
The biggest issue will be locating an engine hoist and stand that I can use down there. The ones I use up here are being used already, so I couldn't move them. A minor obstacle though.
Hopefully, that answered your question.
