NOS 4wd Fan Shroud 1969- 1972 and Blazer parts

[Todd68Chevy]

I do not have pictures available at this time but I picked up some parts along with a 72 Blazer chassis. I have not messed with any 4wd or Blazer items and would like help on the value. Here is a small list.

NOS 4wd fan shroud- part #3901443 from what I have seen when I did a search on here they are all over the place from $100 to $200 but did not see where many have sold. Is $150 a good price or high or low???

Blazer firewall/ dash/ windshield frame area: the firewall does have a rust spots on both sides on the flat firewall. The windshield area looks pretty good but does have a couple small areas that have rust holes. Dash has not been cut for a radio but does have aftermarket a/c holes in it.

Blazer 4wd rolling chassis: it has the transfer case, front and rear differentials (with front disc. brakes) and driveshafts. Crossmembers are there. Frame looks good to me except the front frame horns have been cut on at sometime in its life. Does have blue lock out knobs if that matters.

Blazer sunvisors. Mounts look nice but the vinyl has some issues

Blazer seat belts: both inner belts are there and the right side retractor but the left side retractor is missing.

Fuel tank fill spout and vent tube.

Thanks for any help with pricing and extra information on these items. I will post pictures tonight when I get home from work if my internet is working.
