Often, they don't give the values of the internal capacitors in the IF cans; so, you may have to guess at it. If no values are given, you could try connecting variable trimmer capacitors across where the old capacitors went, adjust the trimmers for best results, remove and measure the capacitance of the trimmer, and replace with fixed capacitors close to the measured value of the trimmer capacitors.

I doubt you installed an electrolytic backwards. Had you done that, it would have likely blown up instantly. I suspect one of the new capacitors either blew up or something else smoked.
