I need your help fellas.. about a 75 Blazer

[Patriot]

Here is the story... I have an old friend(he's 71yo) who has a CRAPLOAD of cool cars. He has 5 K5 Blazers. 2 1975s and 3 around 77-79. He has this one that has no motor or tranny(no big deal, I have many) but the problem is the truck is in REALLY bad shape. The top is perfect and the floors from the back of the front seats and rockers are COMPLETELY gone. He would probably just give me the thing because today he offered me his 79 K5(REAL NICE RIG) for free. I LOVE K5 Blazers and already have 2. I wouldn't mind having more. So here the question.....Do they make COMPLETE aftermarket panels for these trucks. Meaning can I or SHOULD I restore a FULL TOP Blazer????

I already have 7 Trucks/Blazers and a FSJ Golden Eagle Jeep. Do I need more. I can't seem to complete my projects now.

Thanks guys. I know you guys have the answers.
