May70 do you need one specifically for a 4L80?

I have one and it is installed with a 4L80, I bought it very early when you had to order a separate spacer for the trans mount. The 4L80 require a 1 inch spacer. I didn't buy the Holley one, I made one from 1" aluminum bar stock.

Seems like you could order any of them they have in stock(after typing this I went and looked and it looks like none are in stock....)

Come to think of it I think I told you this in another thread...
