My works 91 manual that came with the car originally arrived today and as I've been finding out yokomo had 2 issues of the instructions. One came with the 91 and then the variant that came with the late 91 and the 92.
This is the later version as it has the 92 front and rear shock towers in so now I know it's a 92
You can see the variants in the shock towers here from Fiber Lyte
Need to get some of those ordered to go with the rest of the new stuff for the car that should be landing in the next couple of weeks, can't wait to get started and get it back in the track
