Another somewhat related Cruisair door hint!!! Many Cruisairs that I have seen have window sash locks on the bottom of the door to keep our old flexible doors from pulling out into the wind-stream at cruise speed. The Cruismaster solved that by having a rod that connected to the door handle and extended down into the bottom sill when the handle was in the closed position. It is out of sight and usually never noticed. I have a Cruisair door that has been modified to do the same thing, so it can be done. I have not taken the door apart, but I suspect that it is just a slightly different bellcrank on the inside of the door. For anyone doing a door rebuild or repair, it might be a nice addition to a Cruisair. _______Grant.
