Alright, after much craziness and MANY conversations with CRL here is the scoop:
(short take: Correct part # is GB0X46R)
CRL, and any distributors using the CRL info have had the window crank information screwed up.
The pictures CRL had associated with their GEARB0X46L and R were reversed AND the descriptions for the parts were identical an only referenced the FW620 window. Lots of missing information.
I received a call back from CRL yesterday and had a great conversation around improving the customer facing information to include all the windows these gearboxes are used on. They also contributed listing the proper gearbox as a replacement part reference on the window page itself.
So, the CORRECT PART NUMBER for the FW904RS (arguably one of THE most popular van conversion windows over the past 20 or more years) is GB0X46R - note that the 0 is a zero.
I have one available now and can order more. The least expensive approach will be to accumulate pre-orders so I can have them all shipped to me at one time since CRL charges more than it really costs to ship these out. I can then ship these first class mail and help everyone save a bit. If I do it this way I can offer these from CRL for $45 including the shipping. If a one off from CRL drop shipped is needed then the cost is going to be $55 to cover what they charge.
I will work on getting this added to our BlingMyRig.com website to facilitate ordering. In the meantime, post up here if interested in getting one.
Cheers! Ray
