Title: 4 speed conversion
Post by: Jason Goldsack on March 10, 2009, 03:24:20 PM
Has anyone done a 4 speed conversion on their C.. Will any other bodies pedals work or are the C's ?

You need the pedals from your year C body....a 3 speed on the column was available in 65, maybe AZBlackHemi Chris knows where some are....

also better check to see if there are any differences in power brake vs manual brake pedal ratio (throw) ...I know in 1964 there was...

I did a three on the tree slant six to a 440 four on the floor on my '66.

What do you want to know other than finding a pedal assembly is next to impossible and finding a transmission hump is impossible....

Any pedal assembly 65 - 68 will work.  Good luck.
And before you ask, NO!  Nothing from a B-body will work without some refabricating.
Should you hit the the mother load and find a pedal assembly, and fabricate your own tunnel hump, you will have to remove the driver's side fender to get to the area of the frame where you weld on the Z-bar pivot.
Plus there's a zillion other little things.

That hump was originally available from Harms Automotive and ONLY Harms Automotive.
He held exclusive rights to stamp those puppies out.
Unfortunately, while he held those rights, he only popped out a few at a time when he felt like it.  Sometimes, the lead time was OVER  a year.  Then a couple of years ago, he stopped selling it and inquiries to him from people looking for the hump went  unanswered.  Evidently, somebody bought the tooling or rights from him.  Glad to see they're available again.

And yes there is a different pedal assembly for manual barkes VS power brakes...so you will need to know what you are buying.
 
There was a set on E-bay a couple weeks ago that went for under $100!!

The difference between the manual and power brake pedal assembly is simply the rod that goes to the master cylinder and that part can be easily changed out or modified.

Harms Auto was a Collaboration between Scott Smith & Domingo from Lima, Peru.   Domingo made the parts down there.   Scot acquired the original samples for the parts to be reproduced & distributed them.   There Was "a parting of the ways" between them & Domingo retains the parts end.    He uses Resto Rick now for his US distributor.

The parts are top quality.   We've bought a few.

Scott's gotten into Carb resto's & is one of the best as well as a real gentleman.    I'd send anybody to him that want's their carb to look & function like new.    We sent him a 69 AVS & it took a bit over a month.   Came back perfect.   He communicated all the way through.

You gotta admit the C-body floor hump isn't exactly a high-demand part,    Might not keep a bunch in stock.

Scott jerked me off for almost a year on that hump before I eventually got it. 

When I ordered it, he said it was "in stock".  
Delay after delay after delay, I would inquire about my order.  He never would give me a straight or honest answer.
While it was "on order" with him, I asked him (pleasantly and politely) in person when I saw him in his booth at  Mopars On The Strip, when was I going to get it.  His response was short and rude.

Sorry.  But that was my experience. (http://www.massmopar.com/yabb/Smilies/angry.gif)

And yes, the hump was top quality when I finally got it.

Yep  There is a difference between the power and manual brake pedal.  I am converting a pedal assembly from manual to power.  It can be done, it's just a PITA

I'm not sure which is which but one is a manual brake assembly and one is a power brake assembly, and as you can see the mounting point for the clutch and brake pedals are in different spots as well as the point where the rod for the master cylinder/booster mounts on the brake pedal.

I humbly submit that TC and Polaraco have shown me the errors of my ways.
Never too late to learn something new by being among the best of the best. (http://www.moparfins.com/forum/smileys/smiley4.gif)

I'd also guess the set with the pedal dress up kit is the PB unit.

Actually after looking at the pics the bottom pic, with no dress up, is the power brake booster and it actually hooked up to a booster.

You can tell easily which is which by where the brake pedal pivots.    The Higher pivot point is the Power pedal & Lower pivot is a manual pedal.

The leverage Ratio's are different between them.    High pivot should be about 3:1 & the lower pivot is closer to 7:1.

Example,  if the distance on the High pivot from pivot to pushrod hole is 5" & overall pedal is 15"  divide 5 into 15 = 3:1.      Same for the lower pivot,  shorter distance say 2"from pivot tp pushrod  into the same length gives over 7 :1.

Went through all this in converting my car to manual,  you need at least 6:1 for manual brakes.
