gear vendors
Hi Guys,
Just read the post about the o/drive, yes the`re made in england by laycocks and shipped to the states. The clever pieces are the castings for the adaptions to either the autobox or the manual box. I`ve had one for the last 4/5 years with no complaints. Mines in a 71 b body and the only two bugbears were getting the right speedo drive gears (OCW does these, GM by the way) my own fault i changed axle ratios after fitting the kit and gear vendors after sale service is IMO not great, the other pain was I was running a full 3" stainless exhaust system with a cross over that had to be redone using an H pipe because the crossover sat where the overdrive sits. The instructions in the kit are okay and you`ll love having six speeds or a three speed with o/drive. No probs with fitting just make sure the clearance at the end of the input shaft is set right. I run mine behind a 511CI wedge with a six pack to 3:55:1 8.75" axle, oh yea you also have to get the prop shortened and the vendors comes with a 1350 style yoke (I changed both ends to 1350 s)
Hope this helps
Regards
Dave

Cool. That is even before I fitted mine I think?
I had problems getting the correct 90 degree speedo drive adaptor. But their after sales service for me was very good.
My main problem was the tailshaft adaptor pulled the trans output shaft to the rear, removing any end play on that, and forcing the overrunning clutch to wear into the rear of the trans casing.
This in turn may have damaged the torque converter due to metal in the oil and that in turn may be what damaged the thrust bearing and surface on my crank.
I always tell people to pull the trans apart when fitting one just to check the output shaft clearence.
Even with all the hassle it is still one of the best things I ever bought for the car and as a bonus it allows me to use the 4.30:1 axle gears which are ideal for my car.

I belive the gear vendors is based on the largest laycock DeNormanville design.
the one used in mkII transit vans. J type
this was also used by Chrysler and AMC
these come up on ebay from time to time approx £100
the only issue you have is getting the adaptor to bolt it to your gearbox
however that is not necessarily an issue
because the company that took over all of laycocks tooling can sell you a front so that the box can be mounted independently of the gearbox
you end up with two prop shafts one from box to unit and one from unit to diff.

yes alright if you have a 727 i have a bizzare thing called a borg warner single rail
basically a gearbox designed by BW Australia to fit Chryslers fords and Leyland P76s. looks like a ford capri box but isn't.
I like the idea of a gear vendors but i don't like to spend.

Might have a good deals on HID xenon headlights in 5 and whatever inch and 7 inch sizes for our cars.
300 times brighter and 45% less power draw , in proper domed sealed beam style lenses with hi/lo beam
Quad lights ( Challenger, 71 Cuda) will be more expensive, but to be honest you only need dipped as the main will be redundant they are so bright.
As is the case in my Skyline
Variants are avaliable hi and lo beam separate, or Hi/Lo on with main beam with single lamps
Anyone interested ??
