Cooktop dimension woes

[TRStech]

I recently looked at a old GE cook-topMod# JP661 BOC1BC and the cost of repairs warrant the retiring ofthis antique. The unit is out on a ranch several hours from our shopand I failed to get the dimensions. Just wondering if anyone knows ifa standard 36” cook-top will drop in? Don’t mind cutting out justdon’t want to come up short, old counter tops can be difficult tomatch. Any input is appreciated.
