I tried to borrow one during my engine build, no luck. Ended up using a 2x4 and just light taps working it in. Make sure you use Red threadlock compound on the edges where the seal meets the housing, or you'll have an oil leak like i did...
I used an old main seal ring turned backwords with a 6"piece if 4" pipe.chunk if 2x4 in the pipe and tapped it on.Bscicly duplucating the propper tool.
