Most of the 77-78 tables had the same ball catch, I have a bluetop that has the older leg style and older ball catch. Wish I knew more about the specifics on that table. I have restored a few TS tables and most of them are coin-op (i prefer the stoutness). Havent found that part anywhere. From the pic you appear to have everything you need but the ball catch. Try to find a coin-op TS on CL in bad condition and scavenge parts off it.
Great looking table, man. That is IDENTICAL to the one I grew up on. Lost mine a few years ago. I love TS tables. Nice to see one in such good shape still floating around. Please take care of her!!!
