Hi David,

        Dennis,  just did this to my 85 with engine and transmission out.  I don’t know the exact product yet,  I’ll get all that info when the van returns.

But, perhaps he will let you know what he chose to use.

If not I’ll report back when I have my van back.

Has anyone come up with an alternative insulation?  I saw some ideas on another site, ranging from having nothing to using closed cell spray foam (does not absorb water) to fatmat.  None of the posts mentioned long-term success.  I do not plan to pull the transaxle to do this, so using spray foam would be very difficult.
