the torsion bars on my 4905 are in need of repair but I'm not real hip to this set up. they have either pushed up through the floor or pulled the floor down according to which end there on. a guy I met the other day said I could replace the lower arm on the door with a hydrolic closer for a car hatch back and do away with the torsion bars. any body tried this or have any experience with this? I also seen where he used a strap hinge on the articulator part of the door mechinism. fastening one on each end of the flap to the top of the bay and then to the flap eliminating the need for the rubber hinge and it seemed to work fine. He has a 4903 which is the same as a 4905 but never had a tag axle and that bay goes all the way through. can I cut the frame for the tag axle out and make that bay go all the way through? need all the storage space I can get. | ||

Ron - The tag axle on a 4905 was an option, and is/was completely removable. Just be careful and study how GM put it together before you take it apart. There's a fellow named Ed on the Yahoo GMC busnuts board that makes stainless steel hinges for the baggage bay doors to replace the rubber ones. Can't find his email address at the moment, but if you post an inquiry over there, you'll get a response. It's not uncommon for the torsion bars on your model coach to "modify" the floor, as you've noticed. Another project for you!  I've seen the gas struts used on the 4104s & 4106s, and have heard about them being used on the Buffalos, but haven't actually seen one, unfortunately. . .  HTH, RJ PD4106-2784 Fresno CA | ||

Yes, you can eliminate the torsion bars, I did. Get in touch with ED Gallant at: edannbus@aol.com I highly recommend the hinges that Ed makes. They fit in the same slot as the rubber. He also makes the brakets to install the struts and this set-up has worked very well for me. John | ||

Yeah, do it and do it now. The change makes pleasant doors, and relieves the floor stress also. You will have to put in a floor where the tag axle was, most just use treated 3/4 plywood, but you can get a bay floor from a junk bus and install that too if you wish. | ||

The struts in place of the torsion bars sounds great. Does anyone please have any more information on what type of struts to use and any mounting considerations. My floor is all warped from the stress just like Capt. Rons. | ||

I have some info on gas props to lift up your bay doors. Let me know if you want it. Can fax or e-mail. Rich 800-468-5287 | ||

I have them on my Crown "Trunk" door....very large door....probably 4' high by about 6' feet long...+-; I would do things differently IF I were doing it again: Double....or even triple the weight requirement if possible. In cool and cold temps, the gas struts just do not hold the door much more than at 90 degrees from close. In hot temps, with some encouragement, the door will stay above a 90 degree, but not enough to keep from hitting one's head as one approaches the trunk. Austin Hardware will do a calculation for you and tell you exactly which struts to order,.......BUT...... I have changed them out twice ( not their fault) simply because I did not have the experience to say "double the weight of the door"...their schematic will show you EXACTLY where to mount each end of the strut....also. they now have a strut that can be "locked" in place FWIW RCB |
