I only find different types on ebay. Searched here and found no info. Need to order this week. I'll be using a BMR 4L80E crossmember bracket.

Thanks.

I cannot say which is best however I will say I am not a fan of poly mounts in general as many find they have excessive drivetrain vibration transfer to the chassis with these,GM made that soft gushy sometimes liquid filled mount for good reason even though in fact it cost considerably more to make than a poly mount.

Yes, I heard from too many people the same thing...poly = vibration.

Will a factory 4L60E tranny mount work just fine...?

Yes should be fine IMO

I went to the parts store and bought a stock 1978 GM truck mount.
