915 Bellhousing Cradle

[Clatter]

Here I am, enjoying the mounting of my 915 transaxle...

Now, the cradle, (the part that ties the frame horns together at their ends),
Has some aluminum blocks that butt against the trans bellhousing.

And there are four round rubber mounts, that bolt to the cradle.

The bottom two rubber mounts are threaded into the blocks,
But the two on the sides are not.

Should I drill and tap the blocks, so the two side rubber mounts can thread into the blocks, like the bottom ones do?

-and-

Should I also drill through the trans at the bellhousing, and through the blocks, to bolt the blocks tight to the transaxle?
(like you do with a beetle or 901)

Or is the thing just supposed to 'float' there between all the mounts?

Got a diagram showing the best way to mount?

Thanks.

P.S. Love the kit! :-)
