An original Puretech strap. Modern batteries are too long to fit flush on the chassis with the cross bars, and the strap is a bit short for the fatter cells. Modern Pure tech goodness, with some vintage for comparison: Side by side, the new one is about an inch longer, and the blocks match up size wise. These are actually more like the older blocks which are metal pinned rather than having a plastic bar molded in to attach the straps. The new one mounted in a jrx-pro. Modern battery fits well. Nothing to keep the battery from sliding forward on a hard hit or nosedive(I'm the king of those), unless you use servo mount blocks and strategically place the servo. http://www.puretechproducts.com/
They are not pictured on the site. I emailed Dwayne via the contact page. I included pix of some of the vintage NIP straps I have had. He was quite surprised that I was not only interested in the older stuff but that I had found them NIP. He said he could make some up, I sent off a check and this is the result. They would probably be better about 1/2-1" shorter overall, but they still look good to me.
