Part No. and suspension question?

[alltide]

I need the rubber air cleaner seal flange for a '74 LS4 and need to know if it is the same original part number that is used on the 350? Also I was able to find my tank sticker but it is in poor condition, one item appears to end in 07, if this is the off road suspension and brake package offered in '74 how would I identify this option by looking at my car. :confused
Thanks in advance for any help you may provide.

The correct rubber seal is not being reproduced and the original part is long discontinued. The service replacement part is available from all the usual vendors, but is supplied as a flat length of rubber strip which needs to be cut to fit. The ends are then taped together requiring a special type and width of tape.

As far as I know, the original seal was the same for all engine models in '74.

Can't help you on your suspension question, I've never seen an original example. On your brake calipers, do you have one pin that holds the pads in, or two?

The "07" could also have been "C07" hardtop, if your car has the attaching provisions; options are normally shown in alphabetical order on the tank sticker.
