Motor Mounts
This is probably about the hardest part of the swap.  I justed used a 3/8th inch piece of steel and cut out the measurements  showned on step 1 of the swap.  To get the correct measurements, I used a "dumby block" (completely empty 2.8 block), and s-10 or Camaro frame mounts bolted to the motor. Lowered it down into the engine bay, marked the holes on the steel and drilled them with a drill press. This procedure took about 2 days.  Also you will need to notch out the frame mounts on the chevette shown in step 1.
 

Transmission mount/crossmember
A chevette crossmember and transmission mount can be used here.  To make the chevette pieces work you will need a 1/8th inch steel plate to extend the transmission mount rearward about 1 1/4 inches.  This can be seen in Step 5.  Four holes will be needed to be drilled.  Two to bolt the plate to the crossmember and 2 to attatch the transmission mount itself.  The transmission mount holes will need to be offset to the passenger side of the car.  To make the job a little easier jack up the tail stock as far as it will go and bolt the plate to the tranmssion first.  Next hold up the transmission mount.  Then bolt the crossmember to the car.  Last line up the chevette transmission mount with the crossmember and mark the holes and drill.  The steel plate will only need to be 5" x 2 1/2".  You will need 1/4 inch spacers for the crossmember to lower it down to the correct hight to the transmission doesn't rub the tunnel.
 

Driveshaft
The chevette driveshaft slides into place without any cutting needed.  I don't know how I did the mounts correctly enough for the driveshaft to work with out any cutting.  I guess it was just luck.  Before I made the motor mounts I figured I'd need to cut the driveshaft so I did not take it into consideration.
 

Shifter, Linkage, Speedometer Cable
No "re-working" of the chevette shifter is needed.  The shifting rod between the Shifter arm and the transmission shifting arm will need to be shortened, easily by just screwing it in as far as it will go.  You should be able to shift all gears with no rubbing at all.  The speedo cable is just long enough and it screws right into the th-200 tranny.  I'm not sure how off the tranny will be.  I guess I'll see when I take it through town.  As of right now it is way off.
 

Alternator bracket
Simply use a chevette alternator bracket.  Cut off the pointed park of the bracket.  And line up 2 holes with the 3 holes on the passenger side cylinder head.  The belt lines up pretty perfact.  There's no real hard work involved here.
 

Radiator/Electric fan/hoses
Try to find the widest radiator that fits between the frame rails.  That is about 23 inches.  Mount it in the stock location.  Mount the biggest electric fan in front of the radiator using any kind of mounting stuff.  Wire it to a toggle switch or how ever you want to do it.  For the radiator hoses.  I just purchased a bunch of hoses from the junk yard and spliced together what I needed with a peice of exhaust pipe.  Or you can buy 2 short peices of flex hose and connect them that way.  I went to cheap rout.
