Just thought I'd throw this out there and see if anyone else has installed a set of these. I like the way this set goes together. It looks pretty strong to me. This would be for my 78 LS3 swap project. http://www.cachassisworks.com/Attachments/DataSheets/59XX_g-Connectors_DS_WEB.pdf I'm wondering about exhaust clearance. They offer the parts separately and it looks like the sub frame connectors by themselves should fit no problem. I'm wondering though about the Cross Connectors, and drive shaft loop. I plan to run long tubes and 3 inch collectors. I may just pull the trigger and get the sub frame connectors and wait till I get the motor and exhaust set up and then see if it looks like I can fit the cross connectors and loop.
