Works really well. Too bad the radiator I purchased is too small

Bushings were very close to original shape and size and good quality
Very solid rubbery feel and they fit the lower part of aftermarket radiator perfectly. Top bushings needed some easy trimming.

Fitment for my 69 el camino was to big

Great quality, but only worked in lower location
Quality is great, typical of Prothane. My only reason for a lower rating is that all of the pieces included Prothane 7-1711-BL only work in the lower mounting locations on my '87. They are not shaped correctly for the top brackets. I can probably modify them, but for now I just kept the stock ones that were in 'adequate' condition. I believe the stepped ones shown in PROTHANE 7-1711 listing are what I need, but I didn't order those as I do not want red. Honestly surprised that they have the same base part number, but are not the same shape and fitment.

No more loose radiator.
