Ran into a snag tonight installing the center spool. The single-speed shaft and attached outdrives stick out further than with a regular diff. This means the dogbones are now too long to fit. Did some browsing around and found some shorter dogbones from JQ Products "THE car" that will fit.
The bad news is I'll have to wait to test out the spool now. The good news is I pretty much needed to replace the stock dogbones anyway, pins were pretty worn down. The JQ dogbones were actually cheaper, and also available in red which should look nice with all the other red anodized hardware I got on there.
Champ, that is nice craftsmanship. It reminds me of my build. Here is my GTP II. I subjected it to the same carbon fiber make-over with the exception of the shock towers.
