Help, Bucket seat question???

[chevy111]

I have a 71 blazer and recently pulled the buckets to reapholster them. But the new covers are not the same. My buckets have metal backs and are different looking then the 69-72 backs. Those have 6 screws mine have 8. Mine are also really squared off at the top but the 71-72 s thin out a little at the top. Anyone know what year these are for.
Here are some on ebay for sale. Mine look like the blue ones. The white ones I am almost sure are the right ones for mine. Anyone?????

White ones

The blue ones actually look like they are out of a van...or at least the older vans that I see around here.

They were bolted to the floor in the right locations. Are yuo sure they're from a van? They flip forward. Mine look just like the blue but have the proper brackets under them.

someone swap just the seats and leave the original bases maybe?

I dont know. I looked at a panel van on ebay and the seats look similar. Do you think the bases will work on other seats then blazer seats. I really want to stay original. Should I replace them?
