4spd swap checklist for a 68 Dart GT 318/904

Maybe it was mentioned but I did not see it,,,, and having the motor out will make this easier, dial in the bell housing with the bell mounted and torqued to the block.
Manual transmissions are much more sensitive to alignment than automatic transmission are.
There are several sources for offset dowel pins if needed.
RobbMc has good ones.
And just because a crank bore is drilled to depth that does not mean it is honed to size for diameter. Ask me how I know that.
With a crank that did not have a bushing in the crank bore I will always carefully measure the diameter prior to pressing a new bushing in.

I’m gonna be using the later roller bearing. The clutch alignment tool that I bought from Brewers is just a repurposed 23 spline input shaft from a transmission.. I would think how that fits should give me an idea how well it’ll fit or it at all for that matter.

It’ll be a bit more work but I figure it would give me a good opportunity to deep clean and regasket the engine. It looks like it has had a valve cover leak on both sides for several years. I’m sure the gaskets are rock hard by now. They could have been changed but even if it has been done a couple of times through the years, it’s 56 years old so.. time to start fresh. I’d much rather try stab a trans outside of the car than under it. Hopefully it won’t open a can of worms that keeps the car down for months.. lol fingers crossed
