If you look back at a post I did a couple of days ago The variable element to element spacing on our DB224E's new from the factory ran anywhere from 62 to 70 inches.
If you do some web searches there are several methods that have been used to extend the short elements. These range from cutting the elements and making a trombone slide arrangement, to inserting a screw in the ends, to using long hose clamps and letting tails stick out the right length. We happened to be fortunate enough to have a welder in the club and he welded short stubs of aluminum tubing on the ends of each 35 inch element to extend them out to the 37 inch dimension.
