Does ANYONE know where the M113BRIDGELAYER kit is?

HELP!!
I've tried for months to locate the old I-CORPS 1/35 M113 BRIDGELAYER conversion kit with no success whatsoever.
If any of you know where I can find the kit new or used or the location of the moulds or any info. on the company please reply.

All help will be greatly appreciated. This version of the M113 was only used in Vietnam and none exist today. I-CORPS model co. ran an ad in FSM in the early 90's but no one I know has heard of the kit or the company since.
If you have any info. however small, please get in touch.
Thanks,

Darren
