HOw much of the horch 15 pe (italeri) parts can also be used with the Tamiya horch 1?

Major gf,
I`ve built the Horch KFZ 15 with and without eduards PE set. I possess the Horch Ia with and without the 2cm flak 38 that Tamiya put out but haven`t built them yet. As far as I can tell the Eduard PE set is mostly "parts specific", bit it appears to me that the windshield in the PE set could replace the clear part in the Horch 1a. Also all of the genaric parts like the headlight covers, some bin latches etc.
I hope this was of some help.
Pete
