Can anyone help identify the front clip in my Merc by this bad picture? Ive been told that it is Chevelle but im absolutely not sure. Year. Another question: I need new rims for it to but i don't know what to look for. Like to fit some classic caps later on. Can i use wheels from like a van? Much easier to find here in Sweden...
That is a later style motor mount on the frame. Can't say if it was put on an earlier chassis, but it is likely a later one.
Chevy vans are 5x5" pattern at the smallest, and that's probably a car clip which is going to be 5x4.75" presuming it has the original rotors on it. On the other hand, all sorts of cars can supply plain steel wheels for it. There again you have to watch because some of the cars are 5x5 and some are 5x4.75, but if you look at mid-size GM RWD cars you should be okay. I wouldn't be surprised if it's possible to change it to 5x5 pattern rotors just by swapping parts, maybe using 77-90 station wagon or Caddy/big Buick/big Olds bearings and rotors, but that would take some research on bearing diameters and hub depth to figure out. For as many things as GM made the same, for years, they sure liked to throw in something different; my own driver for instance, if equipped with 4-wheel ABS the spindle is about 1/4" longer and the rotors won't quite interchange to rear only or no ABS spindles - the difference when you screw the nut on is like 1/8", enough you can grind the slots in the nut to make it work, but it's loose on the spindle because the bearing's not seated.
This isn't a great picture, but here is a 78-83 Malibu/Grand Am frame picture for comparison to yours: Don
