Firstly, I know you already have a manual tensioner but I believe it is possible to remove the compressor but keep the existing automatic tensioner for the aux belt ....you just need a shorter aux belt. The vast majority of the weight savings are from removing the compressor anyway.
I tell you this because to fit the idler you need to put an M8 bolt in a threaded hole that has been exposed to road crud for the last 20 years (I.e. currently un used). If the engine is still in the car you can't get a tap on it. The only option is to make your own tap from a short M8 bolt by cutting some slots perpendicular to the threads. It's a very fiddly job n even identifying the bolt hole in the first place is a bit of a pig ...just depends how patient you are!
Anyway, I did manage it but did think afterwards my time could have been better used on other things. I think I used a 20mm or 25mm bolt. Servicebox will tell you the correct size. You can't use the hex bolts from the aux tensioner because you can't get a hex spanner on to them as space is so tight.
