Very nice looking piece! That certainly gives more clearance.
New build A833 18 spline with Gear Vendors OD.

I’m jealous!!!
The driveline guy local to me doesn’t do aluminum so I’m going 3.75 4130.
I’m hoping maybe he started doing aluminum. If so, I’m on that lie flies on poop.

What is the OD ratio of the Gear Vendors unit?

Small progress today. I swapped the lightweight steel flywheel for aluminum unit. Installed the BBL clutch assembly and bell. Hopefully this is the final installation of the trans and GV unit. I had previously only installed the bell without the clutch, knowing the trans would be in and out for fitment purposes. Trans and GV final install should come in next few days.
Just curious, but how do you arrive at that final drive ratio?
After many bourbon, LOL! Just kidding, good catch, Rusty. I fat lingered my post. The ratio is .78:1, making 4.10 final drive 3.19.
I edited the previous post with the error.

I just wanted to make sure I hadn't been doing it wrong all this time.....because Lord knows that could have easily been the case. LOL

Very cool project! I want a thrill ride!!!
The rear transmission mount was swapped for a new shorter one that I found at a swap meet. Listed as an A body mount, I don't know year or application. It is shorter than then one I had. This dropped the unit just slightly, enough to do the trick. This prevented me from having to elongate the transmission crossmember bolt holes for added clearance, as suggested by GV.
How is the GV unit operated? Electronic switching? VERY clean installation, btw!
Lordy. Lemmie get a magnifying glass out. lol I see it though from the illustrations. Thanks! Looks like a quality unit.
I know it took forever, but I took it for its first drive last night. I have not yet wired the GV, but according to the owner of GV, there is no harm in driving as a 1:1 unit. I am very pleased with the results.
For those curious, yes, it only takes very minor clearancing of the floor around the actual GV unit with a large ball pean hammer. Additionally as per my previous posts, illustrating the minor grinding on the GV adapter housing in the area where it passes through the transmission cross member.
The GV supplies a 24" speedometer cable extension. This proved far to long, so I had a 16" made. This fit perfectly.
I used some other A body rear transmission mount that was JUST slightly shorter, this provided the necessary added room.
I had the Dana 60 built concurrently while I did transmission and GV install. It turned out excellent. I measured the driveline angles with diff in car, then tacked in place. We pulled out again and did final welding. Angles are as follows.
Engine, trans, GV = 2.7 down
Driveshaft = 0.7 up
Diff = 0 degrees.
I chatted with the owner of GV about this and his suggestion was to try it as is with no pinion angle shims. As per his recommendation it seems to be perfect, so far no vibration at any speed. This is a huge bonus as my car always had a driveline vibration that drove me nuts. Very smooth and very quiet operation.
The aluminum flywheel is awesome! Im so glad I went that way. With the 4.10 gears, it rolls out like my old flywheel and 3.23 gears. When you roll on it it revs "like a die grinder", to quote another member. Again, very very smooth on the highway. Engine idles excellent, even with a 239-241@.050 with 106LSA.
This project took me a while due to living a real family life with work and other commitments, the outcome is excellent. I am very pleased with the choices made.
Here is the proof that tunnel rams and aluminum flywheels can be street friendly in the right combination. This car is a sweetheart to drive.

Glad this all worked out for you. Now go do some gear jamming and some long haul cruising, and enjoy that beautiful Dart.

You're gonna love that GV overdrive with your 4.10s. That's the same gear combo I have in my Barracuda and it's the best upgrade yet. I've been driving mine for over a year now. Though mine is behind a 727 rather than a manual.
