[DeTomaso] Seats - don't make my mistake

[Bill Lewis]

I took my almost 40 year old seats to the upholstery shop.  The seat covers are still in good shape, but the seat foam had turned to dust.  So, I had them re-foam the insides of the seats.  They did nothing to the seat covers  
I just put them back into the car and I cannot sit in the seats.  The new foam added too much heighth in the seat and too much depth in the back.  My head leans way over for me to sit in the seat.  I have to take them back and explain what the problem is and hope they can correct the problem.
How will I know how much foam the seats should have, or how much for them to take out.    Thanks, Bill Lewis
