is there such a thing.......

im having the worst time trying to get the last thing I need for my lt1 swap..

I order a 4l60e tailhousing from a guy on ebay... he send me the same old 700r4 housing for a cable drive speedo...

Now he says he can send me the sensor that fits in the larger hole, but needs a new plug, is this going to work with the 40 tooth reluctor on the 4l60e?

can anyone show me where to find this part in some online store..

thanks
