I received the belt kit. Sadly, it does not fit mine. Good news: I found more detailed data and a possible source! I'm also checking to see if I can obtain a refund on these belts, and whether the vendor has access to the correct ones.
1) A nice belt length calculator is at https://sudenga.com/resources/figuri...tween-pulleys/
2) See below for my calculations for my VCR -- Mitsubishi HS-U560
3) While my exact VCR belts are not listed ANYwhere, another web site provides exact specs on belts for a huge number of VCR's, and my own VCR specs are very close to two of the belts they list. See https://www.smcelectronics.com/vcrbltsq.htm
