Built engine bottom is support rods S01-620-432 which attaches to keel and bottom of the PSRU. Built the engine horizontal support rods S01-620-2003 which attaches to the top of the PSRU and the cross on the keel.
There was some confusion of the part numbers needs to construct these parts. The alum tubes had different numbers that did not match. However, Dan Bank did send a pair of support rods from their test setup.
These were built early to be painted with the keel.
