What is the diffrence if any between a K5 designation and a V10 for a blazer. Noticed the V10 designation while looking up parts for my 90 full size blazer the other day at auto groan. I thought they were all K5's

C/K5/10 was the designation for the 73-87 Blazer/Jimmys and R/V10/1500 was for the 88-91 Blazer Jimmys. The pickup line kept the C/K designation, and the old bodystyle picked up the R/V. Basically there is no differences
