A855 - 5 Speed

The runout I have most often seen across a broad spectrum of manual transmissions, 855 included, is .010 or less total runout.
I hadn't heard of that before Jamie Passon told me to check it.
I bought Zero degree (straight) dowels and a PAIR of each offset from (the best) Robb Mc. I took it a step further and sprung for 2 different Browell's alignment tool/jigs that almost completely fill the hole in the selected bellhousing (in my case 1 MOPAR and 1 Pontiac) you mount it securely and then look at the slight gap all around. If the gap is larger in any area, the bellhousing has to be shifted in that direction.
