If you look real close you'll see 2 holes in the pump are threaded to 3/8". The threads aren't always easy to see. I won't say it's impossible but in over 30 yrs of rebuilding torqueflite's I have yet to see one that didn't have threaded holes. Some smaller slide hammers are the correct size and thread. The front band lining isn't real thick even when new. I haven't actually measured the thickness but I'm sure it's no more than 1/8"
