Here's a few pictures of the DeMarrias conversion I did last winter.
The first one (AuxTransP...) shows the paper template cut with a ballpein hammar finding hole locations.
The second one (OC3Tank...) shows an alternate method to mount the gas tank bracket when using early Model A transmission.
The third (OC3TObearing) is the shop made throwout bearing carrier. I could not find a factory one compact enough.
The 4th one (OC3TransSetup) shows using an old block to get measurements
The last one (OC3Transbearing) shows the asembly

Thanks. ......Dave Spitzli
