Are these '72 Big block perches?
 

Found these cheap- I know they are worth some coin if they really are for the '72 only BB.

Can anyone ID without a doubt? I don't want to spring for them if they are '73- up.

yes they are the 72 towers! Here's is a couple of picture of a set I had.

hard to tell from your picture, but 73 up the holes are further apart in relation to the center rib. you need to get a pic. of the top view, also check to see if they have the clam shells to go with them. hope it worksout that they are 72 mounts as you can turn a few bucks on them if they are.

The tell tale sign is the humps, on the top rail part, 72 only have one hump and the 73 and ups have two humps (bumps if you will). So those are the 72 only's.

I told the guy I wanted them, might get them tomorrow night. Aren't the clamshells the same as ho- hum 73- up parts? If so, I can find those by the dump truck load :lol:

Thanks for the help everyone :metal:

Here's everything bolted together. They're for sale if anyone needs them.

Re: Are these '72 Big block perches?
 

Yeah the clamshells are all the same, if you find an old set, energy suspension sells a urethane bisket to replace the old rubber part, just seperate the clamshell (riveted together usually) and install it, sweet find!!


BTW HARTROD how much??

Re: Are these '72 Big block perches?
 

Got 'em. Both are stamped Demco, one numbered 757, the other 758. GM must of had an outside vendor for them?

does anyone know were i can buy a set of the bbc clam shells mine are shot and i can only find the 4 bolt ones or the realy expensive energy suspension inserts. i found a set of 3 bolt ones from ictbillet but the Dimensions are all wrong.
