Trying to find pictures of the “hone o drive” installed on a early Motion C3 Corvette. Any pictures or where to find pictures would be appreciated. I’m back to working on my ‘68 which I have installed a hone o drive unit in. My concern is the drive shaft angle with standard u-joints. I’m looking at going with a CV joints instead oh u-joints, I would like to know how motion did there instillation.
Any information would be appreciated.
i have researched many different articles and still have not found a picture of the hone o drive installed in a c3 Corvette. I have found a picture on an Camaro and some Ford products but no in a C 3. I have the unit installed with drive shaft and all the mountings, I’m not comfortable with drive shaft at that angle I have a CV type mounting for u-joints that I may try later but right now I’m trying to get a picture how it was mounted behind a Muncie.
Attached is a couple pictures that somewhat show the changes after adding the hone o drive. I will get under and see if I can come up with an angle that by adding the hone o drive has created. Does anyone know for sure the angle on a stock Muncie to rear-end? It might be more accrete by comparing the difference between the two.

did you have to enlarge the drive shaft tunnel? I was looking at buying one. I had a line on a few different units. I will try and find the pics I had.
I’ll try and cover a couple questions. In the stock driveline and the offset is 1 1/4” the driveshaft angle would be 2.398 degrees, if the offset was 1 1/2” the driveshaft angle would be 2.878 degrees.
i had to open the driveshaft tunnel in both directions the left 1/2” the right 1 1/2”. The biggest Chang was up I had to remove the emergency brake handle and the mounting bracket.
The reason I ask about pictures Im not sure if they ran the hone o drive straight back from the transmission or was it canter toward the rear-end. The finished driveshaft is only a little over 12” long. My best guess is my current drive line is around a 5.682 degree angle. I’m not real comfortable at that angle, any feedback would be appreciated.
I believe the o/d unit was connected directly from the transmission via a U-joint. If the shaft angle is and issue, the mounting bracket for the Hone-o-drive can be altered so that the offset is split between the trans-to-o/d joint and the o/d-to-differential joint. If the angle offset between trans and diff is 4 degrees, just alter the mounting bracket so that there is a 2 degree offset at both the input and output of the Hone-o-drive unit.
That’s basically what I have I have offset the hone o drive about 3/4” off of centerline. The unit is connected by u-joint directly to the output shaft on the transmission and on the same plane as the transmission. The tunnel had to be opened taking out the emergency brake assembly to get it on the same plane.
Would you post pics of the tunnel opening from the inside? thanks.

I passed on 2 that were below and at $1000. To the OP. Great job on the install. I noticed you have a parking brake still. How is it actuated? I've seen electric mods on here before. Yours looks mechanical
How I’m going to activate it is still up in the air. I fabricated bracket and lever similar to the 65-66 Corvette. I was thinking about using the cable and stock 66 handle assembly. I would need to shorten the length of the handle to make it fit under the dash. Second option would be mount a linear actuator that would be the easiest . I have mounted a linear actuator on the hone o drive as you can see in the pictures to shift between gears which works great. The switch will be mounted in the ash tray out of sight.
I don't know how much force that actuator cable requires, but maybe a door lock actuator could do that job electrically. If much force is required, or much lateral movement is needed, the door lock actuator probably would not work.
