1991 B2200 timing question

Anyone know what are the timing marks for a 91 B2200?The repair manual calls for "A" mark on the camshaft pulley, but I don't have that. I have #1, #2, #3 and #4 with an arrow above each at 90 degree from eachother, and I also have a circle between #1 and #4. What mark should I align to the mark on the housing?
Any help is greatly appreciated.
Thanks.

with the crankshaft pulley lined up at zero in the lower timing belt cover,
camshaft pulley #1 or A mark should be lined up with the upper mark on the aluminum back plate housing.

The lower timing belt cover is off, and so is the big pulley on the crank shaft. Now, the small pulley on the crank shaft (timing belt pulley), has a notch on the back side, and a circle on the front side, right above the key of the crank shaft. I aligned this mark, to the mark on the housing...at this point, what mark on the camshasft pulley should align with the mark on its housing?
Thanks in advance.

if the bottom timing belt pulley is lined up with the housing mark, that's good.
Now the camshaft pulley mark #1 should line up with the housing mark on the top.
Then you're good to go.

Yeap, it worked! Thanks a lot for the help.

B2200 / 2000 Timing Check (http://www.mazdatruckin.com/B2200/B22TimeCheck.html)

I have a problem putting the camshaft sprocket (top timing pulley) back on because I did not mark its position prior to removing it. There is a guide pin on the camshaft that mates to this sprocket. Does anyone know what position this guide pin should be if the crank pulley is already at TDC (12,3,6,or 9 o'clock) ? There are 4 positions that this guide pin can go on the camshaft sprocket. If I only know the actual position of this guide pin at TDC, based on previous form on timing issues, the #1 marking should be at 12 o'clock position. Anyone?

Looks like the guide pin is at 12 o'clock position. Thanks!
