Sadly on a +4 there are (IIRC) two pulleys that the reverse of the belt runs over so any markings are usually long gone before the belt needs changing. Doing an online search, I came across holley.com and their recommendation is: with old belt removed and tensioner at rest, pass a length of string or wire round the pulleys in all the right directions, measure its length and subtract 16mm to determine the actual belt length required. I also read somewhere else that if you cannot find the exact length, up to +/-3% is acceptable. Very useful - thank you.

If 5he marking# are worn away then measure the belt(s).
Width, total length. Those are the basics. Then look at whether plain “V” , toothed or ridged.
You can use those details to get replacements. They are standard dimensions for belts and a motor factor would be able to find them.

Interestingly, the gearbox oil is specified as Lodexol, and actually states “fill with 1.7 litres up to the fill hole.” No mention, as often discussed on this forum of the need for 2 litres due to the 8 degree cant of the Mazda gearbox, but mine was one of the very first with the Mazda box so its possible that the manual was printed for the Ford MT 75 box!
Regards
Doug Checked my handbook today, and it does indeed quote that the gearbox is a Ford, even though a Mazda MX5 box was fitted from new. So dont trust old stock handbooks
