1976 K10 LS swap I'm doing a LS swap, with a 4L60e married to a NP261, in my 1976 K10. I'm in search of transmission crossmember that would work. So far I have only found transmission crossmember for a C10.
Appreciate any thoughts

Depending on the fore/aft mounting position of your engine/transmission, you can use a stock 85-up K10 transmission mount with an 85-91 stock K10 "W" shaped crossmember, or 87-91 "S" shaped crossmember. You will have to drill new frame mounting holes in either case as the attachment hole pattern is different than what was used on the 73-84 transmission crossmembers and frames. This compatibility also assumes you've located your engine/transmission in the stock offset position; if you've shifted it to the left or right for component clearance, you'll need to adjust the the trans mount location laterally by the same amount.
