I looked through my Ames print catalog and noticed they had two Borgeson boxes, one for $399 (manual) and one for $549 ( 12.7:1 RATIO. 3 TURNS LOCK TO LOCK).
The other boxes from $299 up into the $400's were re-manufactured boxes requiring a core charge and core sent back in. I suppose the quality of the re-builder vs Borgeson quality would make alot of the final decision to buy from Ames. On the other hand, curently, Borgeson is offering ther 12.7 box for A-bodies for $467.78 and has a 3 year warranty. Which to get
If I didn't have other priority things to do on my GTO first ($$$$), I would opt for the Borgeson deal now along with their new rag-joint. FWIW
