I finally unloaded what I thought was my 465/205 combo out of the crate that it came in 2 years ago. Well, it wasn't like any 465/205 combo I'd ever seen before. Upon closer inspection I realized that I have a 465 and a Dana 20. It's not really a divorced setup because there's no driveshaft going from trans to t-case, but there is about a 6" long output shaft enclosed in a tube going between them. I'm not upset about it at all, it was just a surprise. I don't forsee any problems swapping it into my K5 since it came with all the linkages and crossmembers out of the donor truck ('71 K5). It will be kind of unique to have a 465/d20 in an '87 Blazer. Plus, a Dana 20 weighs half of a 205, and I could swap Dana 18 gears into it to get a 2.46 low range, or a Tera 3.15 gearset. Everything I could find about Dana 20's said that they only came behind the 3 speed manuals in Blazers, but this is most definitely a 465. I wonder if it was a special order or if somebody rigged it up themselves?
