I would say that it would depend on your HP and how you intend to drive the car. I personally recommend the plate type differentials more often than not, but honestly speaking, if you are just looking for a bit more grip and you never really jump on the car, then in all probability a TBD will...

Sent you a PM that should be helpful to your question.

It sounds more like a slave cylinder issue to me.

Is the clutch disengaging?

Cam I live in Longmont, CO which is not far from Lakewood. I can probably help you with this if you need it. I ship gearboxes all the time, as that is what I do for a living. Give me a call. (720) 899-6005 phone Sorry I did not see this until now.

The 4.22 ring and pinion is going to make your engine rev quite high at speed, as mentioned about 3000 rpm at 80. The fact that you are running wide open exhaust on the car makes me ask the obvious question, what did you expect it to sound like? I would check all of your mounts to make sure...

I am not sure that 3/4 of a inch is going to be enough to completely disengage the clutch pressure plate, but assuming that it is and you are indeed getting the full throw out of it, I would take a look at the pressure plate and see if perhaps the diaphragm has a issue. Feel free to give me a...

Randy, give me a call and I will be happy to give you all the information on this gearbox. Happy to help, Erik Johnson (720) 899-6005 phone

It would be helpful to know what gearbox you have.

This is a pretty easy conversion actually. Send me a email, and I will be happy to walk you though the inversion options, as well as how to convert it to 2wd. We work on these quite a bit so happy to help. Happy to help you with the information. Erik Johnson [email protected]

You have mail.

I could not agree more with the comments made here save to say this. Synthetics and synchronizers are not usually a good mix. Synthetic oils tend to be more slippery and do not give the needed friction for proper synchro action. There really is no need for expensive synthetic oils in...

It looks like a differential bearing shim to me. During setup it can sometimes be necessary to change these out several times until the correct tolerance is met. This can be time consuming and perhaps one of these fell into the gearbox and we not seen during assembly. Just my thoughts on this...

Yep you can indeed convert this gearbox to 2wd operation. It is one of the stronger gearboxes out there. It may be a tight fit for the GT40, but it would certainly be worth the effort. PM me if you would like more information, as we have done quite a few of these conversions in the past...

It is a roller from one of your tapered bearings, at least I think it is. Difficult to tell for sure, but I would certainly get in there and check everything out before something more important fails. Just my .02
