Anyone ever used the factory rollbar out of a Jeep Wrangler( or similar) in an E.B.? Looks like it would work & you'd get rollbar/padding/seatbelts/overhead speaker bar all in 1 package + save some $$$ in the process. If so, what mod's were necessary?? Thanks & you guys are the best. Wish I had joined 5 years ago when I bought my '73( oh well...)!
