Yes, Chevy is made by gm
Yes they are the same.
Yes and no ......the frame on the 86 is wider ud have to drill new holes in the 77 body for it fit and make different mounts for the doghouse etc alot of hassle but its always possible if I remember right the 80s frames were 6 inches wider cause we tried to put a 88 cab and motor on a 76 highboy frame and it was to much pain so we got a 95 frame its backward from what your doing maybe find a older truck frame close to your year i do believe the 80s rangers had a similar frame width but it wont be as strongly built in my opinion

Yes, both should be interchangable.
(90 + 86) ÷ 2 = 88
88-91 Crx parts will not fit on a 86 crx. The 86 Crx has wider lights.
81-86 are the same. 87 is the same as the 88 supreme classic. 87 grills will NOT fit an 86 without changing the entire header assembly.
No. There are three different tops for the C4 Corvettes, 84 to early 86, late 86 to 88, and 89 to 96.
The short answer to this would be no, it will not fit. Not without considerable re-engineering of what G.M. did. The full size Chevrolets used an "X" frame from 1958 to 1964. The Olds, Pontiacs and Buicks used a standard frame configuration. (Frame rails more out-board) The exception would be Canadian built Pontiacs, which shared the X frame configuration. 1960 Olds 88 and super 88 except Convertible would be the only direct bolt in replacement frame.
no parts for a 89 go thru years 88 thru 91
84.75 is the mean of 88, 91, 74 and 86.
