FT390'' Motor mount issues

ok so i own a 73 heavy f100, replaced almost every moving part on the thing. ran into problems mechanic put a "new motor" in for me while i was gone for work, six months later iv got issues.. pretty sure the frame mounts arnt the right ones, bought a tin man fabrication set from summit racing. they dont fit. need to find a pair, auto fab had some but the passenger side were angled and one side was shorter than the other, which was part of the reason my old system was torqing on me

On 2/wd right side 'passenger side' mounts are shorter than the left side ,engine is offset to the right. I believe 4x4s are too.

Mine 4wd, lifted with R80-15LT buckshot mudders. The offset frame mount is the problem. The frame mounts are offset not allowing for room on the passenger side for my headers. Plus the motor mounts literally shear apart. So my local parts guys who I've delt with for years started digging. The mounts were 2wd. But without a listing for 4wd mounts. So I bought a set off of summit racing but to top that off they don't fot

You may just have to build some if you are trying to center the engine for header room . Just make sure you don't put the drivelines in the wrong place and good luck.

Drive line = drive shafts , old school i guess

Google "driveline" or "driveline shop" and see what you come up with.

Oh ok. I just wasn't familiar with it being called that. I'm not really worried about my driveline. Transmission is centred and shafts are all brand new with spicer joints. The engine mount/ torque situation is causing allot of problems. Flow tech headers don't fit and tried searching Doug thornley fender exit headers not listed. Another problem I live in northern Alberta. So anything from the u.s takes 4-8weeks

Are the summit mounts just the part that bolts to the engine ? Can you use them if you were to build your own mount stands. What is the Summit part number and i will look at them so i can get it in my head what the problem might be .
