Default Automatic to Manual Trans. conversion

Has anyone converted an automatic C3 to a manual transmission? What all does it entail?

Thanks in advance...

Default It's fairly easy

I converted mine by stripping the parts off of a junked 4 speed car. Coverted it in the driveway, hardest part was fabricating up a clutch crosshaft mount. The links mentioned above show the process pretty well.
If you do it "my" way as opposed to a kit, remember to take enough of the the junker's wiring harness so you can easily and properly wire up things like the reverse light switch and the switch that only allows you to start when the clutch is depressed.
I did it about 15 years back, no problems since.
Have fun.

I did my '70 last year (Muncie M20). I compiled a complete parts list with sources and prices as well as a written chronology of the job. PM or email me and I'll send it to you.

If you do go to the trouble, go with a 5 speed overdrive. It makes it twice as good!

I''m in the process of doing this as well. I see that the latest C3 had a bracket that was "bolt on" for the clutch cross shaft. I wander if I could use that bracket and drill through hoes into the frame for bolts. Did you weld your bracket onto the frame?

Hi J-V,
A very good question!
But you've re-opened a thread that's more than 10 years old.
Bruce C hasn't been active since 2009.... he may not see your post.
You might want to send him an e-mail to get his attention and a reply!
Or, you could start a new thread of you're own and you'll get the attention of folks currently active on the Forum.
Regards,
Alan

Thanks in advance...
Not sure your C3 is ? or which manual trans you are looking to install.

This is my 1978 conversion to a T56 Magnum 6 speed.

Not sure if you are putting a 5 or 6 speed in, or have a specific question, but YouTube has some good content/instructions for either of these.
