Flexdiscs are for vibration control, NOT deflection.
    I'm thinking along the same lines, I'll start investigating a U-joint yoke that could work on the Getrag output flange. However it isn't a live axle, the center section is hard mounted to the frame and it has control arms and axles to the wheels.

    The drive shaft will only be 12"-14" long when it's all said and done, plus I'd need to mount another crossmember for the support bearing. I think running a U-joint at trans output would be an easier & cheaper solution

    Me thinks there should be a slight angle, but not 0. Bearings and CV joints need a slight angle so they will rotate in their housing to keep them from riding on the same spot.

    Can you change the lengths of the axles to center the diff?

    I believe in OE trim the first section of driveshaft before carrier bearing is 0 degree, or close. Then the post carrier bearing, U-joint to Diff has the driveline angle.

    I could offset the diff in the frame, but that too would look odd from the rear of the vehicle. The focal point of the rear is that diff with inboard brakes.

    For fun, went a bit goofy on headlight mounting:

    Sick project man. Definitely following this one. The m62 is great engine in stock form. You are going to have an absolute monster! It's gonna be priceless to pull up to a euro car meet in that thing.

    Looks like your making good progress. Might have to take my '33 for a ride(when it's done) to AZ next year to check out your ride.

    It will be necessary as with only one U-joint you'll not have constant velocity, especially at that angle.

    Fuel tank arrived:






    Picked up this three pedal assembly with masters that it's intended use is a sandrail. I liked that the unit is modular & self contained.



    You see there is a clearance issue with the exhaust, the front of the tape line is where the front of the body sits



    Managed to find bolt in masters that have a smaller reservoir, I also like that the lines will go to the rear away from the heat source.





    Clearanced the body to fit over the pedal assembly. Could have been done cleaner but I want the ability to remove the body easily and retain all mechanicals on the frame.





    Put the engine on it's mounting pucks to get a better idea of exact drivetrain height for exhaust clearance:



    You can see a bit of engine tilt back here, the goal will be to have parallel valve covers to frame rails. This will look cleaner and provide the same Ujoint angle on trans output and differential.




    Parallel drivetrain will also increase the exhaust to masters clearance and I may even be able to pull the pedal assembly forward a bit increasing leg stretch room. As is it's not terrible.

    6'1" size 13 shoes. Keep in mind I need to bend and tweak pedal arms to get full swing and clearance.




    I'm starting to get scatter brained looking at the vehicle as a whole and only starting one part of a system at a time, so I'm going to start focusing on one thing at a time starting at the rear. Welding in the rear diff mounting and rear coil over mounting and then working my way forward. I'm going to be losing this shop space at the end of the month, the vehicle will be in pieces in storage until I can line up another shop space so I might be on hiatus for a while. I'll try not to back burner the project as it's out of sight & out of mind, it's important to me to reach a goal this year with this vehicle.

    When I started putting this thing together in my head I always imagined a chopped '32 grille behind the axle. I just mocked the full length '32 grille in front of the axle and leaned back. I'm beginning to feel this might be the way to go. Cleans up the look and gives room for the water-to-air heat exchanger in front of the radiator.

    Looks much better with the radiator in front of the axle, need to have the rake look.
    Hers's a friends '32, not the same as your T-bucket, straight radiator.

    And the one I'm building.

    With the hard top. I'm not 100% sold on the top, It definitely changes the attitude which I like. Even hinged at the rear with removable pivot pins to take off the top it'll interfere with my roll bar plans and change the idea I'm running with for the windshield.







    Picked up a set of aftermarket adjustable motorcycle coil over shocks for the rear. I figure since there will be four of them and since the car weighs next to nothing it may work out and ride okay. If not it's an easy fix.

    After a hiatus I'm back on the project. Losing the use of one shop space, putting everything into storage. A brutal winter in this area. Now found a new shop space and continuing on.





















    My first time welding. Just tacking in bits until a pro can come in with some real firepower.

    Differential mounting:



    Differential cross member and seat mounting:



    Motor mounts, radius arm mount tabs:



    Clutch & brake master/pedal assembly mounting:

    Kinda funny seeing how far back the seats sit without a body or drivetrain.



    Rear shock mounting:

    This is awesome, the engine is a masterpiece. Do u have a estimate at how much power it should make with that blower?

    Thank you. My goal is 450hp...which will likely feel like 600hp in an 1800lb car.
