I'm not far from Angleton (57 nm N) but I can't offer anything but a few ideas... perhaps he could try and contact Bruce Bohannon or another RVer at the nearby Flyin' Tiger airstrip?
Flyin' Tiger is a sweeet grass strip about 10 miles north of Brazoria County and home base of Bruce and his much modified RV-4... I believe there might be another RV or two based there as well. Bruce has gotta have quite the shop and tool collection, plus maybe a spare elevator or two lying around?
Not sure if this helps, but it's worth a shot. Flyin' Tiger strip and contact info here;
