I just had one of those "DUH" moments. I have a small block 727 trans sitting out in my shop with a small block manual bellhousing next to it. Compared the bolt patterns on both the auto trans and the bellhousing and there are no threaded bolt holes on the bell housing to bolt the struts to. The bellhousing on the starter side doesn't even come down far enough for the strut. On the passenger side, the bellhousing has an unthreaded hole but it's not machined for a nut on the backside. So, no struts on a manual trans small block. I'm trying to make my 74 Rallye Charger correct, so I'll reinstall the struts on it. Thanks.
