Wraith II Rear Jacks. -------------------- GTRY 1166 We send herewith N.Sch.4859 showing the rear jack brackets on the Wraith II back axle. The jack itself is that for Phantom III entirely, and we calculate that the clearance under the inflated tyre will be approximately 1.56". If this is not enough the threading on the jack can be modified to give greater clearance. We have set the jack at 6° from the vertical following the treatment of Phantom III, but this angle may need to be modified on test. The jack bracket is very similar to that for Phantom III and is a light alloy casting. Ev.{Ivan Evernden - coachwork} Att: N.Sch.4859. | ||
