Pace desoldering heater replacement?

[qweets]

hello : )

I own a ye olde pace MBT-100e desoldering station; with i believe, an sx-55a hand piece (light grey plastic housing).

The heater needs to be replaced, but they are not for sale anymore in the UK ( except in the US; with big import and handling fees)

I wonder if anyone knows if a newer SX-70 heater will fit an old sx-55a hand piece, if the correct wires are matched?

thanks for any help : )
