Maybe ask your machine shop? The upper tube is an interference fit and goes down far enough to hold the lower tube in place.

I looked again and you are indeed correct that is the tube I need! I see there is a lip down in the block about 3/4" inch that the flange on the end of tube hits against. Makes sense now to keep it from going in too far but allow the top tube to press into the block. My old one must have been rusted in or something since it didn't readily come out. The engine was locked up so that is very likely. You saved me some hassle and now this thing will be correct thank you guys, sometimes its the little things that we get tripped up on!
