The plan is to put an '87 T5 behind my 235.

Trust me, I've spent the last three hours reading about this swap before asking.

I see some people use spacer plates (from Buffalo and other venders) but assumed that was just the easier (albeit more expensive) route, but have read that bolting the gearbox to the bellhouseing without the proper spacer plate does not hold the input shaft true enough and can cause damage to the input shaft and trans bearing.

What are your thoughts/experience?
