Hey all! I recently received a very nice early-to-mid 70's Ludwig Super Classic kit in blue sparkle. While taking everything apart for a good detailing, I found inconsistencies with the tension rods on both the 9x13 and 16x16 toms. The 9x13 has a mix of 1-5/8" and 1-7/8" rods, while the 16x16 has both 1-7/8" and 2-1/4" rods. Many rods also don't appear to be Ludwig. I have a feeling that Ludwig may have used rod lengths of 1-7/8" for both toms. Just to clear up any confusion, we should all be aware that the length is measured from below the collar to the end of the thread. Anyone have some 70's toms they can confirm these lengths with? Yes, I'm anal about these little trivial things and agonize over using the correct parts!! Help me before I lose too much sleep!
