1/2 conversion??

(1/3) > >>

Slingray:
Hi guys,

Just trying to find as much information as I can about the pro's and cons of Mirror Conversions and Chain Drive Conversions when I happened across a third type of conversion which I didn't know existed, a "1/2 Conversion".

Basically I'm wondering what a 1/2 conversion is and how to recognise one? I understand a 1/2 conversion leaves the brake booster on the Left Hand side of the car, similar to a chain drive system. What else is done? What makes a 1/2 conversion different to a Mirror or Chain?

I've been all through this thread:
http://www.nswcorvettes.com.au/forum/viewthread.php?tid=167&page=1

But am still very interested to hear people's thoughts on Chain VS Mirror VS "1/2" Conversions.

Slingray:
Thought I'd chuck this in - has anyone ever considered getting a chain drive converted to full mirror? The interior is already converted, you'd have to replace the steering column I'm guessing, the rest of it would be a pretty standard Mirror conversion?

Just curious. The more I reseach the more I think a chain drive isn't such a bad way to go. But at the end of a day I think a bad mirror will be just as bad as a bad chain. So long as the car has been converted by someone who knew what they were doing you're pretty right.

I think there is plenty of info already on this site about this already.
IMHO chain conversions these days are quite ok - one could be forgiven for thinking this is a half conversion. Bear in mind there is still the brakes to be done, a cross shaft is common on C3s, so brake booster is left on left side and a shaft is used that runs under the dash to operate brakes. The clutch is done the same way, usually a hollow shaft enclosing the brake shaft to operate the clutch. Ever seen a driving instructors dual operation car. clutch and brake pedals on both sides of car. Our beloved corvettes converted this way are the same 'cept we cut the pedals off on the left side!
Then there is the mirror conversion, every thing is moved to the opposite side along the fire wall, inside the car and in the engine bay.
What type of conversion is best? is a moot point. I will say the mirror is the most asthetically pleasing and prolly does better at car shows.
The cross shafts work just as well, I believe some BMWs and heaven forbid Hyundais(?) use these cross shafts.

mine is on LHD and all i can say is that it works perfectly and handles the corners perfecly and very responsive on brakes!

My uderstanding is :-
In a mirror conversion or when the brakes etc are left on the left side but the steering box moved to the right side, the motor is spaced over to the left side of the engine bay and usually a ford steering box is used.  [sometimes a toyota box]  This off setting of the motor usually means that the fan shroud has to be cut and altered so that the fan still sits in the middle of the shroud.  If the brake booster is still on the left this also moves the motor closer to the booster and the clutch mounting is changed slightly.  I'll stand corrected on this if I'm incorrect.

I think thats what is on yours Joe from what I remember.
