The thickness of the gear at the end of the assembly on my old one measured 0.667 and the new one measures 0.590.
The length of the assembly is correct and the countershaft is correct.
Were truck 318 and car 318 tranny the same ?
It looks like the counter gear assembly would fit but what about the effect of the thinner gear.
I am now waiting for the authorization to return the gear, but before I do I want to hear opinions. ....

I have excepted your return request on ebay though.

Let me assure you that this is in no way a critism of you. I would like to use this part if it is all posible and since I am only a hobiest and not a professional tranny guy I have to ask if it is possible to have this work.???
Let me know what you think. thanks
