Manx SR2 Build

Are the frame horns known for bending?
I don't recall seeing them reinforced before....

[MyManx]

One of my frame horns was bent up slightly. Maybe from a previous accident?? I have read many articles from Google and TheSamba that tell about frame horns bending down, usually on Baja cars and buggies from jumping etc. I squared everything up and reinforced with heavy-wall channel. Very strong now.

Finished much needed work inside the tube. Shortened and re-attached the emergency brake cable tubes as well as all four heater cable tubes. I may not use all the heater cable tubes, but now I have the option if I decide too in the future.



Shortened the shift tube and routed the clutch and throttle cable tubes out the back. Installed new fuel and brake lines. Also clamped a piece of poly pipe inside the tube to run my electrical through.



While disassembling the front beam I discovered a couple of broken torsion leafs in the top tube.



I replaced the top torsion leaf assembly as well as all the ball joints and seals.



I remounted the fiberglass inner tub and marked and drilled all the mounting holes around the outside edges, through the fiberglass. After removing the tub again, I drilled and tapped through the steel outer rails. The mounting bolts will now thread through the fiberglass and into the outer rails without sticking out the bottom.

Mocked up the fiberglass body using clecos.



I only received a couple of body supports when I bought the car so I am building the necessary reinforcements as I go.

Battery box.

Mounted battery box.



Completed rear support brackets.

I used this simple setup to transfer the location of my roll bar support pads to the inside of the tub.



Now the holes are drilled in the correct location, through the tub and the rear support brackets, tied to the upper shock mounts.



Completed front support brackets between front axle beam and front clip / trunk area.



From underneath, looking forward.

Looks like you're moving right along, and will some awesome engineering and fabrication skills!

Finally made some time to get back at it.



Stripped the fiberglass body back off.



Finished the work inside the tunnel, painted it and buttoned it up.



Reinforced the bottom of the frame head.



Added new floorboards.

oh my goodness what a terrific build. I got exhausted just looking at the photos. I never saw a tunnel shortened the way you did. it was most clever. your fabrication skills are over the top. people often ask why great cars cost so much $. I think you have answered that question.

Adding universal sliders to the seats. I'm concerned about headroom when the targa top is installed, so I'm trying to keep the seats as low as possible.



I made them as low as I could and still be functional.





Seat mounts welded in on both sides. Added support blocks in between.



Finish welded the vertical triangles at the rear of the floor pan.



A nice cozy fit and the sliders are fully functional.



Made some brackets and hung the tilt steering column.

Made a couple heavy duty roll bar anchor plates.



The fiberglass tub fits neatly around them. They are angled back to match the back wall of the tub. This also maximized the seat travel.
The roll bar and the seat belt retractors will bolt the these.

Awesome build & very well thought out!!! What are the bucket seats you're using out of originally???

[MyManx]

Thanks Mike,
I bought the seats new from speedwaymotors.com. They are "Scat ProCar Pro 90 Series".

[MyManx]

Fitted the roll bar to the body and located seat belt anchor points.



Everything functions well. Will eventually disassemble and finish weld everything.
