Here's what I have for the 92 extended cab. https://photos.app.goo.gl/sxLUR2Br3jMQd65P7
I've got a regular cab Longbed 96 that I plan on doing a similar swap on. I'm going to use a 54 GMC 2 Ton Front clip and bumper on it and I have a cut down flatbed from a grain truck that I'll be using for a bed.
