i see the richmond is about $3000...is there any chance of finding a good used one? and if i do...are they expensive to repair if i got one and it needed work?
also,does anybody know about any other sites to check out the richmond??
the richmond site kinda sucks and dosnt really tell much...

also...the Tremec TKO 5-speed...whats the deal with that one??
where do i find info online about that one??
what do some of you know about that one??

also...are there any other options???

with a 2.7 or 3.08 rear end you still have an aggressive first gear and a very low RPM at cruise fourth. It is a direct bolt in with no mods.
Last time I checked, it was about $1500.

Bolts into the C-2 and C-3 without modifying the frame- although an auto. trans. removeable crossmember would be helpful (the '79 was an A/T 350).

To install the 6-speed, the transmission mount must be moved to the rear 3.75”.
This has been accomplished by several methods. Some cross-members have a
removable center extension that can be removed and re-fabricated. Some
extensions are welded in and have to be cut out and re-fabricated. Another
method commonly used is to cut the center section out of the cross-member and
weld end plates with bolt holes on each end, then fabricate a removable center
section. This way the motor does not have to be pulled to install or remove the
transmission. Some have also cut out the complete cross-member and made a
frame to frame bolt-in crossmember. On some of the Corvettes, a pulley for the
emergency brake cable needs to be relocated. When relocating the transmission
mount, check the driveline angle in the car. If the mount is too high, the
transmission will hit the car floor pan, and it will change the drive shaft angle,
which could cause a vibration.
Some Muncie and T-10 transmissions have a 10 spline input and 27 spline
output. Some have a 26 spline input and 32 spline output. The 6-speed has a
32 spline output, so you may have to change the drive shaft yoke. For a
Corvette, the yoke has to be open end. A Chevrolet number for this yoke is
3930827. The hub on this yoke may be too long for the Richmond 6-speed. The
hub length on this yoke should be cut to approximately 3” long. When installed,
2” to 2 ¼” of the hub should be in the transmission, which would leave ¾” to 1”
from the hub shoulder to the tail-housing seal. In most instances, the drive shaft
length is close enough to meet these dimensions.
The 6-speed uses the same bell-housing, flywheel, pilot bearing, throw-out
bearing and pressure plate as the T-10 or Muncie.
The 6-speed can be supplied with a 10 or 26 spline input. If using a high torque
motor or going to change the clutch anyway, use the 26 spline clutch, because
the 26 fine splines are not cut as deep into the shaft as the 10 splines, which
makes the 26 spline input 40 percent stronger.
T-10 or Muncie rubber transmission mount and speedometer parts may be
reused or new parts are available from Chevrolet.
The shifter will be approximately 1” to the rear of the current location and may
have to be cut 1” from the backside of the shifter hole under the console, but the
shifter will fit the console with no modification to the console.
