Hi Guys, New here. Thanks for having me. I am currently swapping the T-15 in my 72 commando to a 72 nailhead TH400. It’s seems like I am missing the crankshaft spacer 3184864 that I have seen in other posts. I have the cast iron spacer installed, removed the pilot bushing and installed the sizing bushing, when I mount the tranny the torque converter is approximately 3/4” away from the end of the crankshaft. Any help would be greatly appreciated

Javwetwotone just pulled a 304 out of his '72 Commando and his has a flat crank shaft flange. Does your crank have a flat flange or raised flange? IMG_3113 by Rick Jones, on Flickr To run the Nailhead TH400 you need this spacer for the crank.

Thanks for the reply I have the raised crank and the correct flexplate. I believe I only need the crankshaft spacer that you are showing. Any leads Thanks again

BTW, that crank spacer works on either crank.

Picked up the spacer yesterday from Digger on the Old Willys Forum. He told me he has 1 left if anybody is interested. Also over 10 acres of Willys goodness hiding in Wrentham Ma.
