1974 Boxer Rear Suspension Question

On a 1974 Boxer, Should the control arms bushings on the rear suspension be rigid babbitt type? (as on the front suspension) - or unitized 1 piece silent block type (as on later cars)?

Thanks Guys!

 

Thank you Cavallino70. My car does have one piece silent bushings on the rear. I don’t think they have been replaced - but perhaps they have. My parts books show one piece, but the books also show a publish date of 1976. There were quite a few update changes up to 1976. And with many more cars being built as 512 cars in 1976, the one piece bushings would help cut costs. I was thinking perhaps they should/could have been babbitt type in the earlier 365 days.

Do you have further information on this?
