Seeing as you've Tposted the front this will do you no good- but as a future referance, the Grubee motors fit so perfectly onto a Cranbrick that I will shim my next build on the back mount to adjust the chain. Currently I have two of those "College Cranbricks" with the green fenders... as well as two of the 'Kareoke Cranbricks' (Japanese word that means 'tone deaf') and two of the 'Panama Jacks'... and six Grubee kits... waiting for me to get off my a$$ and do the build. Gotta knock out six 'Howard Sprocket Mounts' before I can start- I HATE the rag mount.
Yes, Ive gone into the assembly buisness. Got a backer.
