That sounds like a great build. I toyed around with finding a clock spring and nothing seems to fit. I ended up moving my adapter plate position and now the adapter is about 1/4" larger than the NRG adapter. So this left room for me to push through some wires. It works great, but i still have to rely on the coil cables, which I do not mind and they do not bother me, but if you can develop a clock spring that fits the NRG adapter, I will be your first customer. That would be a game changer. Good Luck!

@@scottcerreta1724 hey there scott, well good luck with the clock spring idea! I found a manufacturer in china who can provide the spiral cables in any length up to 10 feet! I have a few samples now, one has 12 conductors in it, seems to be the most that can realistically fit within a approx 1/2" wide cable. I will be working with a cousin of mine to 3d print a clamshell type housing for the cable like oems have. One side fixates to the column, the other spins with the wheel. Then will need to print some grommets for the spiral cable to exit/ enter the housing, and transition to small gauge wires. Thankfully the steering adapters for our vehicles (most 60s to 90s gm, and aftermarket like ididit) have enough of a cavity inside of them. Makes me wonder why this hasent been attempted yet. Ive only played with 3 oem clocksprings to study, and 2 of them were so close to fitting inside the adapter that it makes me think there has to be an oem one out there slim enough. But i think the money spent in buying a bunch to test from a junkyard is better spent developing this custom version. Even if manufacturing it seems like too big a task, i can always share the 3d print files, a link to the aliexpress seller, and some easy to follow pictorial instructions . Would sure be nice to have a hidden solution for some steering wheel buttons. Ill keep plugging away at my.endeavor and be in touch again when i have something tangible yo show! Cheers bud

@@HAMMER_2.2 Thanks for the update. Project seems like it is moving along. i would love to buy one from you is you can build it. i also added a ididit steering column with one touch button ignition. i think this aids to the modernization of my project car. i asked ididit if they have a clock spotting that fits their column and they said no. i was bummed because they have a cruise control lever option but apparently the electronics are on the column side and not wheel side. bummer. i hope you can master this. it would truly be exciting and i think you could actually sell these! there has to be a market for them.

i hope you love it as much as i do

Awesome. Totally agree. If you want to drive at freeway speeds you need a TH400 and GV or ditch the TH400 and get a more modern L60 or L80 4 speed tranny. I love my old school TH400 so went with the GV.

I’m thinking I might have 4.11s lol I was told 3.55:1. I’m at 3k at 60 as well. 396 bbc Th400 and a 12 bolt in a 69

IKR? I've been looking for a solution since I had my rear axle replaced, and all they could find was a .355, instead of the original .307 gear ratio for my 1990 Dodge Cummins (Newer transmission, etc.). Want to keep the truck simple. Trying to get the .307 gear ratio back in my rear end.

Awesome! I hope to hit the track this year. I have the Elky in pieces right now and hope to get it back together before the end of April.

You can certainly use it to split gears all the time. You wont hurt it if you're under 1200 h.p.

i think it is electrical. i only have one speedo sensor and the GV wires are connected to the DD box to share the sensor reading since both sensors were identical and i verified this.

​@@scottcerreta1724 I found out to get the gear vendors overdrive not to shift into overdrive early I had to disconnect my speedometer cable. At first it was shifting into overdrive at 25 mph now it's 45mph.

yes with one exception. the GV computer is connected to a speed sensor. your speed needs to be above the threshold to activate ON. typically around 40mph. the computer will also deactivate the overdrive automatically if you dont. typically around 30mph. that is it.

If you want all 6 speeds available with the Gear Vendors, you will have to manually press the button to engage the overdrive at the end of each gear, then as you reach the max RPMs again, you'll have to manually disengage it at the exact same time that the transmission shift to the next gear, and then repeat for each gear.

Yes

exactly

@@scottcerreta1724 Cool! I could use the extra OOOMPH for my E4OD work truck, now I know that thing will then become an E8OD once I get a GV kit. Thanks for helping me confirm my question, Scott! 😁

Love it. It is still as fun as the day I installed it. I have 8k miles on the motor and GV now. Everything is holding up nicely. A lot of those miles are freeway miles where the OD is on. I have made three oil changes on the unit now.

@@scottcerreta1724 Iam going with the gear vendor myself I don’t like computer transmission 🤣🤣 to many break downs

@@mauricedade1347 I hear ya. I think you will enjoy it. Are you dropping that it into the 72 impala? What motor and tranny are you running right now?

@@scottcerreta1724 yea In the 72 impala ima go 427 small block with a th400 373 gears

@@mauricedade1347 luv it. Share some pics when you get it rolling with the GV.
