    i just installed a motor in my newest project and am trying to do this on the cheap so here goes.......the new motor didnt have a temp sending unit in the head but my old one did, so i figure no prb ill just pull the old one and install it in the new motor, well that ends up being a problem, the hole is too big for the sending unit, apparently chevy has a big and a little sending unit. so would anyone happen to know what size the big and little sending units are? i am just gonna run down to the hardware store on my way out to the shop and grab a brass reducing bushing if someone can throw me the sizes i need. Thanks
